Probably the best tutorial in any game jam game. Crazy stuff for a game jam. It does get a bit repetitive, but it's only normal for there to be limited content in a game jam game. The only thing that bothers me is that the theme 'darkness and duckies' is just slapped on there. Like why are we collection duckies when the gameplay feels like factorio/clash of clans.
Besides that it's a really great game, like crazy stuff!
