Thanks for the feedback!
We have a post-jam build that is bug-less so there's damage indicators, the player controls aren't slippery anymore, and the 3 worlds we put together may actually be played (currently it breaks after the 1st world). I'm also writing a devlog about what has been fixed, and (more importantly) a whole lot about where we could take the game from here in order to flesh it out. So if you enjoyed what we had here, maybe keep an eye on this after voting for the game jam ends!
