Thanks! As for the music, I really wanted music on the level as well, but it was already hard to find the one for the menu, and I didn't think it'd suit the game itself. I also wanted to do as much as I could myself, so all the sfx were made in sfxr (on my previous jams I downloaded a lot of them).
But, if you reaally want music in the game, you could try to solve the easter egg I hid, it's probably way harder to solve than I intended, but you can give it a try if you want...
