Outstanding submission - graphics are simple, but really nicely done and consistent, aesthetically. Gameplay is very compelling, and I found myself having quite a few stabs at it before giving up, haha.
My biggest complaint is missile spawns - sometimes a missile will spawn so close to you that you cannot evade it, which made some losses feel unavoidable. Otherwise, gameplay would’ve been a good 5. Would have loved to see (or hear?) music and sound FX in the game, I think it would add a lot, but given the time constraint, I see why you omitted it.
Awesome game!
