Level 4 got the better of me, I'm afraid, but this is neat! I think I hear GXSCC being used for the music? Either way, it's fun. One slight complaint is that you use the mouse for the UI, but the keyboard for gameplay, and switching between the two isn't ideal when I just want to hit retry immediately.

It should be possible to trigger the buttons with Enter/Spacebar but I guess that's not so obvious or maybe it didn't work for you for some reason? The sound effects I made with ChipTone by SFBGames and the music is "Boss Battle V" by nene from opengameart.com. Thanks for playing!
