Love it!
My only suggestion is to add a quick replay button after you fail.
Otherwise, it's a great game, and I’ll definitely add it to my collection! <3
Quick replay probably would be a good idea to add. I may have to look a bit at that after the jam.
As a small note, both the start screen and the game over screen are wired so that you can hit space to continue through them, so with hitting space twice after a game over you can get yourself into another game fairly quickly.
