Currently among my top picks so far. It just hits everything right, from the theme to the gameplay and the references. It absolutely captures the feeling of a souls game and keeps it simple enough to be enjoyable in a jam context. I really like the combat and I'll definitely keep playing this in the future to try and get the crystal sword! Great work!
Small bug report section: if you run into Biboo at the start (when she runs towards you) it's possible to get shoved under the stage and it's impossible to hit her from there, and the only way to get hit yourself is if she spins. I can recreate this bug more consistently with the pickaxe than the shovel (not sure why). Also (in the first phase of the fight) sometimes I am hugging the boss so close that the overhead and side slash don't connect even if I don't dodge. Might be also the angle I'm at. Not sure why that happens too.
