This game can be played with either keyboard and mouse or with a game controller!

Before starting a level, you must choose up to 4 pilots to complete the level with. In the level, all the pilots will shoot simultaneously, each with their unique pattern. All are vulnerable to enemy hazards, and if a ship goes down, you lose it for good. The pilot in leader position will define the squad's formation and how they move together. The leader pilot is also the only one whose overdrive is being charged at any time, as you deal damage to enemies. You can cycle your pilots and set whichever you want in leader position at any time during the game, using the controls described below.

keyboard controls:

  • The arrow keys to move the ships
  • Shoot with X
  • Swap the squadron's leader with C (this changes the formation and which overdrive is being charged)
  • When the leader's overdrive is ready (bar is full next to their portrait) use it with V

game controller controls:

  • Move the ships with the Left Stick
  • Shoot with (A)
  • Swap the squadron's leader with (B)
  • When the leader's overdrive is ready, use it with (X)


If you'd like you can come to our Discord to talk about the game, share your highscore, discuss strategies and/or get advice! We'd love to know who's your favorite pilot and what boss you hate the most!

forced inclusion

oh believe me, no-one is forcing us to do anything at all. indeed we're very happy to be doing whatever we want. 💁‍♀️


i talk about the game characters, and as a trans girl, LGBTQ+ and black color people community inclusion is just forced in this game

oh well i guess it's the inclusion jail for us then. no regrets tbh, we had a lot of fun designing diverse characters and we think more devs should do it. 🤷‍♀️


why? what's the importance bruh


are the characters like lgbt? or am i confusing something kfjd


oh yeah, it's not really mentioned anywhere for the sake of subtlety, but they're all gay af

Does it matter? How does it affect the game?


It doesn't affect gameplay, but some people will be glad for the representation. :)





ok the character design is good and the graphics too i will try this game someday!!!!


Definitely going to try this someday


Pixel art and music are both glorious. Controls are simple but nuanced, based around controlling a formation rather than a single fighter. You've got nine pilots to beat three levels and three bosses. The levels are the same every time but the trick is to try to work out the best combination of pilots on each level to maximise your sustainability and efficiency.  As each pilot has totally distinct strengths, weaknesses, weapons, and controls, this leads to far more replayability than you might expect, and there's also a pile of handicap-based challenges you can tack on.  Might have liked another level or two but there's hours of entertainment here as-is.


Spectrum as in Autism?

Spectrum as in the visible light spectrum, but we don't mind you reading it that way. :)


I lost 3 of  my comrades to a single attack once the stasis wore of and had to take on the final boss all by myself. We have won the battle but at what cost :'(
