For whatever reason, I couldn't damage anything, at all, whatsoever. The screen also seems to slowly rotate for some reason, so it was nearly diagonal on my longest playthrough by the time I died. Could be an issue with the OSX export, since I'm playing on a macbook.
The aesthetics are charming, and the art and music make me feel like I'm playing a game that could have come out when I was very small. It's lovely and I hope you do more with it.
