Absolutely awesome game, I recently found the Game Jame version and loved it so I was amped to see this released. I would snap up a full version in a heartbeat.
There have been a few bugs (as expected for a prototype, so I don't mean that negatively) but I just beat the Gloom and ran all the way to the end and I can't draw a hand or play a card or anything at the red locked door. I can't tell if this is an intentional end point or not. Usually there'd be a message if that was the end of a demo/prototype so I wasn't sure if this was a glitch.
