This is a really cool idea, and the execution is really good (especially the visuals from a clarity perspective, but also the sound and gameplay too). I think having some sort of invincibility available on the boost would be good, since I didn’t find it very helpful later on due to the crowded-ness of the screen (if it does have invincibility then I wasn’t quite sure when/how). Also, the bomb powerup is useful but the others don’t feel all that helpful, so I think something like having different tiers of bomb spawn would potentially be more useful.
Really really well done!
