I got the impression that the version for the competition is more cheerful and dynamic. The environment is better, but where did these cubes come from, they don't fit in any way. This "trail" from objects and the ship, it also seems superfluous to me, if there were some ability, as a result of which this trail would remain. The boss fight has also become boring, long and it feels like the game is starting to be even slower, as if in jelly. So far, I did not go further than the first boss.
The font is not very good. And it is better to return the settings to full screen mode and back.
Good luck in development =)
