I'd like to correct a small point. The error stems from something being removed at the last minute. I'm with my colleague to confirm that the game is in a state that saddens us as much as it does you, and that we are actively working to resolve it.
Absolutely all the planned features are already implemented, but the original tutorial feature wasn't finalized, so it was removed, creating a gap in the storyline. I ask for your patience. Even though the jam is ruined, you'll have a playable version soon.
