It's a 2D traditional platformer that's 2 player local co-op. Just escape from the dungeon. Find the key & get to the door.
My daughter is 6yo and she said she wanted to make a game. So she started drawing in crayon some levels, characters, and monsters. I thought that was super cool so I made her artwork into a real game for us to play together. I also consulted her on most of the mechanics too.
It works with 1 or 2 players on keyboard, but also works with 2 gamepads. I highly recommend playing with gamepads.
