Oh, hey! I haven't actually gotten any feedback from the Patreon build yet, so this is super welcome. I'll try to address these points in order:
Orc invisibility:
Thanks for pointing this one out. Silly oversight on my part. It had to do with the body of the orc being "shared" across all the other orcs on the level, rather than individual. So one died, turned invisible, and all the others did too. Easy fix.
Inventory bug: Keeps me up at night. I'll hunt that white whale though.
And, agh, sorry about that end-of-content softlock. It must be missing some flag. Normally those reset you, ending the run. And, even worse, you're absolutely right.
Ending the run after having opened that key door would've unlocked the sorceress start. There's not a mountain of content hidden there right now, so I wouldn't stress about trying to do it again. But you would've gotten to start new runs of the game with some different default cards and different starter gear.
Final point: Game-Overs
Uh, yeah. I'm actually pretty receptive to this one. By and large, I tend to prefer making content part of the gameplay. Making people have to lose to discover new scenes (outside of roguelike long-term meta progression I mean) is something I kind of dislike. But maybe some stuff on a per-stage basis would be a good inclusion. Either way, I want to touch up the tutorial & game-over screens a bit.
Anyways, thanks for the feedback & for playing.
