love this concept! being able to explore different little worlds is so cute.
some notes:
-i'm not sure if the fishing mini game is working? i tried pressing e on top of the fish but nothing happened. i think the instructions on that one could be a bit more clear too.
-during the maze world, the grub keeps getting stuck at the dead ends of the maze. it might be better to turn it into a collectable rather than pushing it around. i think the maze should be difficult enough on its own.
