Got to 88 after a few runs of trying to figure out the mechanics. It could do with some explanation, even just some simple in-game images on a bespoke screen somewhere.
I think the main wonky aspect of the mechanics is that you seem to NEED to take damage in order to DEAL damage? Which I think would work better if there was SOME way to heal that didn't entail needing to be angry.
Either way, really interesting little project, best of luck to the dev.
