Use the Left and Right arrow keys to move. Use the Up, Spacebar or Z key to jump! It's not demonstrated in these given (empty) rooms, but you can also climb small slopes and steps by walking into them.
~by anna~ This is a version of my game Hatlight with empty rooms and no light / darkness system for ease of remixing into your own games. The Walls sprite contains the solid parts of each room and the Scenery sprite contains the background parts. The map in the first room shows how the rooms are numbered. Feel free to remix and share!
