I very much appreciate your review! Even the critique feels nice to read hahaha. We've put our blood and tears into development of this project. I might even say we got a little bit overly ambitious. I believe we should've spent more time fixing various bugs and issues. So much you can do in three days...
We plan to release / update the game with various tweaks after the gamejam!
(btw, the hidden health bar issue, as much as it can be annoying, fortunately the boss bar is just like your healthbar, but inverted)
