More about the game!

An inspired love letter to some of the best side-scrolling games ever made

I grew up playing games like Salamander/Life Force, Gradius, R-Type, Super Aleste, Einhander, Ikaruga, and more. Interstellar Sentinel features tight controls, digital & analog stick (PlayStation & Xbox controllers verified), stylized beautiful art with lite anime inspiration, and a rewarding experience that becomes more challenging as your skills grow.

Designed For Flow State Gaming:

Also known as being "in the zone," this mental state refers to a player who is fully immersed and intensely focused on a video game. In this state, the player experiences a seamless and effortless gameplay experience, losing track of time and achieving peak performance. It is characterized by a perfect balance between the player's skills and the game's challenges, resulting in a deeply satisfying and enjoyable gaming experience.

Monster Trophy System

A hand-crafted dynamic difficulty system. This system provides gameplay depth, layering, and secrets. The more your skills with piloting and weapon systems, the more the game changes to provide you with new experiences, including hidden miniboss challenges across the levels. 

Be Thrilled:

This game will ignite your senses from the very first moment. Excitement will course through your veins as legions of demonic entities swarm towards you, your fingers will dance on the controller, flight maneuvering with precision and speed. The intense action, visually stunning graphics, and immersive sound effects will keep you at the edge of your seat, fully engaged in fast-paced battles.

Feel Empowered:

Your Gun Portals are a powerhouse of deadly weapons designed to keep the core game loop changing and challenging with never-before-seen weapons in a shmup. Over 55+ weapons are at your fingertips; as you collect weapon power-ups during intense battles, you'll experience a surge of empowerment. The feeling of turning the tables on hordes of enemies with a barrage of laser beams and missiles is simply euphoric, making you feel like an unstoppable force. Experience the unique flow of weapon cycling and adaptability to become a master of battle rhythms.

Be Immersed:

Mesmerizing environments that will draw you into its sci-fi fantasy universe. From giant kaiju bosses in cosmic landscapes to undead guardian dragons, each level is intricately designed to create an immersive experience. The seamless integration of music and sound effects adds another layer of immersion, making you feel like you're part of an epic battle opera.

Feel Relaxed and Mindful:

Amidst the chaos of intergalactic battles, you'll discover moments of zen-like focus. As you dodge incoming projectiles and navigate through tight spaces, you'll enter a flow state where your mind and body become entirely absorbed in the gameplay. This meditative quality allows you to momentarily escape the pressures of daily life, providing a welcome respite and a chance to recharge.

Features:

Earworm Original Soundtrack:

• Legendary original composed soundtrack from the brilliant mind of Chris Huelsbeck (The Great Giana Sisters, Turrican series, Tiny Thor, and more) comes a modern retro tribal drum synth chip tune feast for the ears that captures the struggle of heroic friends straitening out a twisted world

Unique Gun Portal Design & Weapon Point System

• Rapid Shot, Power Shot, & Auto Shot spatial design provides spatial choice gameplay. How you position your DrBossKey relative to the weapon points allows for advanced piloting techniques to dish out damage. Advanced techniques like point blanking (think of it like sticking a shotgun in the face of an ugly demon and pulling the trigger for maximum impact), Power Shot alignment (charge up, 10x more powerful shot compared to the Rapid Shots, often with piercing), and Auto Shot utility (near field damage, homing missiles, plasma stasis damage fields) give a great mix of core gameplay choices.

• Your wingsuit reactor core vulnerability point is the key to weaving through the bullet hell battlefield. Don't be intimidated by some of these bullet hell fields, they are not as hard to navigate with a modern player hit box as you would think.

Extensive Weaponry System:

• Rapid Shot, Power Shot, Auto Shot Form a "Weapon Set"
• 19 Weapon Sets & over 55+ weapons to be mastered 
• Unique core loop gameplay experience with a high rate of weapon shifting that ties back into all key systems. Flow is in mastery of the Gun Portal weapon systems
• Gun Portal weapon sets are designed to scale in utility and versatility, with your base weapons being powerful to avoid “Gradius syndrome,” where losing your weapons makes you want to start over because your basic weapons feel like throwing wet noodles at hungry demons
• Weapon Downgrade system, you can dump your weapon sets to keep playing with your favorite weapons for the situation. Dumping weapons also keeps your chain combo multiplier going and offers great risk vs reward scenarios

Super Weapon System:

• Destroying enemies unleashes their soul bits, monster soul essence, which power your super weapon
• Generate temporary invulnerability field
• Cancels enemy bullets to generate higher score rewards
• Produces Monster Star Gems to collect for bonus points
• Unleashes the stored-up monster soul essence, which in turn regains soul essence which can let you chain supers together
• A full super weapon bar is a terrible thing not to unleash on the very plague of demonic enemies that you harvested super weapon energy from

Wingsuit Repair System:

• Part of being a badass flying hero is knowing that your suit can take a hit or two, sometimes even strategically (hint hint) 

Monster Trophy Medal System:

• Screen clearing enemies and achieving high scores produces Monster Trophies. Monster Trophies spawn more challenging and unique enemies
• Monster Trophy Medals are earned when defeating Monster Trophies, which in turn power up your Chain Combo meter
• Monster Trophy hint system gives you a sense as to how much more there is behind the curtain of the universe 

End Level Ranking System:

• 7 possible ranks from D to S+ tier ranks that drive dynamic challenges, minibosses, and may even unlock the secrets of the universe

Deep Scoring System:

• A dynamic score system that factors in Chain Combos, Monster Trophy Medals, Boss Time Bonuses rewards, Power-up, Surviving, and more that rewards players that are not traditional score chasers
• Score transcends mere digits; your accumulated points serve as both additional lives and the path to advanced gameplay rewards like mini-bosses and the glowing admiration of your Twitch followers

Enemy Chain Combo System:

• The Chain Combo system starts when destroying enemies and you have to keep destroying enemies every 6 seconds before the chain combo meter ticks down to keep your high score going for maximum fun and prizes

Pacifist Mode Challenges:

• Each level contains the pure joy and anxiety of surviving. Rule number one of Pacifist Mode, survive; rule number 2, see rule number 1
• On completion, provides higher tier powerup weapon set drops
• Gain an extra life when activating it
• Gain a temporary core shield hit point

Local Leaderboards:

• As your skills progress, your score is the key to measuring that progression. Chasing the 1 credit clear (no deaths game complete), and S+ tier ranks is a goal worthy of your gamer mantel. Etch your initials into your Hall of fame

Difficulty Select:

• Choose from 3 levels of difficulty, Casual, Normy, & Heroic

Level Select:

• Play and practice any level right from the start... you can even peek up Santa's Chimney 

Optional Tutorial:

• Learn the basics of the Weapons, power-ups, and Monster Trophy Medal system

8 Levels Packed With Shmupping Goodness:
