Wait i really forgot to put sound ? XD since i code with background music i guess it kind of slept my mind, well i guess i know what to improve, i tend to forgot about sound effect. I opt for no shooting because with the fps mechanic it would hurt visually and make even harder to dodge incoming one (also to avoid the game to run at low fps) Thanks for playing

Thanks! Incorporing the change of fps was the hard part since if it isn't low enough there just no instability, i got some idea like dodging beam with lag (it's in the game but the actual beam is invisible and isn't working) and in général having low fps isn't good and just annoying so how to make it fun ? I'm not found of it myself XD. I try my best to make it feel "fair" but i agree that bullet with lowfps are a pain since they just teleport due to lag.

True that having a death count help for training. I didn't make it for that initially. It was because of the simulate fps, it can make it really hard to dodge bullet that should be easy. I found that making a limit number of life would be really frustrating

Glad you like it! I'm also somewhat happy with it. The patern are just simple circle that rotate, I kept it easy for my first bullet hell (and didn't have much time on hand to do more sadly)
