thank you very much for the feedback!
The constantly holding control was indeed part of the theme, as the enemies spawning above you can only be killed with Enter (as an enter key prompt on screen should have shown, so that might not be clear enough as well), forcing your right hand to stop aiming for a bit and quickly press the Enter key. The fact that you're forced to switch between these tasks is the main out of control part.
And I know spamming works and it did not help I merged the melody ánd the beat at the last chorus. There's a whóle to learn about making rhythm games for me besides these 48 hours if I ever want to make a decent one.
the bullets sometimes collide with eachother and had different speeds, which wasn't really my intention at first but seemed like something people could play around with if they wanted. The game over screen still showing up after a game over is new for me, so thanks for finding that one!
I might release a web build of the game to which I might make slight improvements to. Weather or not I will, this has been very usefull feedback, so thank you!
