INCREDIBLE visuals! I'm trying to get into pixel art and this was fantastic. The music was great too, and together they felt super good, well done!
This is already peak visuals for me, so this is just nitpick, but I would LOVE if the band was animated. I know its a lot more work, but when I saw the hotdog alien animated but the band being static, it felt a bit odd because the band is such a central piece.
And maybe its on my machine only but I've hit a bug where the first time I have to hold a key down, my screen freezes for a while. This happened on both levels
But these are minor things, overall this such a solid entry, and seriously one of my favorite pixel arts I've seen. The feedback when you hit the keys is really good and the game felt challenging but the atmosphere is great, I had fun playing it!
