A scratch dare project, demo. I really like the concept of this game & decided to release the demo until I have finished some more levels. For every 12 love-its I'll add one new level. You can also remix this project, add custom maps and tell me where the key and portal should go, so I can add it to this game. This should've been 1 sprite 1 script, but got lazy and decided not to do it... Why are you still reading? :P
