Thanks so much, that means a lot! You're definitely not supposed to fall out of the map, thank you so much for reporting that. Apparently the MapData.txt needs to be alongside the .exe, so that's been fixed in the uploads! A main menu and boss dialogue has been added as well, so hopefully the current upload is already a lot more cohesive and game-like than last night.
We're really proud of the quality progress we've made over past jams, so it's awesome that it came through. Thanks for taking the time to play and give feedback :)
