My main feedback would honestly be that the music is very loud, and I wasn't able to turn it off (though that might be a wine issue instead of an issue in the actual game; but I don't think that's very likely).
That said, it's definitely a fun idea!

I'm using Arch with i3 for windowing, which means it's using X11 and scales the applications directly after they are opened if it can (due to i3 being a tiling window manager).
Also, it's all good! It *is* a game jam entry, and if bugs like these weren't something to be expected; and this one really isn't game breaking either.
