Thank you very much for the feedback, I wasn't aware of the closing related crash, but it seems to be related to the fonts, I'll definitely be reworking the text so that wont happen in the future.
There is a tutorial room to the left of information room, that has a battle test and talks about dodging, shields and status effects, I'm not a big fan of mandatory tutorials in games but making it easily miss-able is a mistake on my part. I'll rework the maps to telegraph entry points a bit better in later builds.
Thanks again Colin you're feedback is invaluable for a first time dev like me.
