Thanks for the feedback! You are right, getting the mechanics themselves down left little time for smaller details.
I like the idea of the timer changing speed, but I did intentionally make it the exact speed it is so that it would line up with the music. If it doesn't line up, then timing it would be much, much harder (I guess I want to make it harder anyway, so I'll actually play around with this idea).
And yes, after the jam (after the voting ends) I intend to give this game weekly updates to make it more complete ;)
