Cool game, the sprites were well made and the color choice is good. the mechanics are all there, but it was really hard.
Because i did not get used to the control scheme at the start of the game I did not know how to dodge or move and got wrecked. The bullets also seemed super fast and hard to dodge. If you keep working on the game after the jam, try giving the player a little time to get used to the controls, and maybe slow it down. As a rule of thumb, you want the game to be way too easy for you, so new people will be able to play it until the end.
The idea is good, just needs more time and playtesting.
