I made a game ( Space Is Limited ) where you have only one screen, so you can focus on the puzzle platforming.
but the main only one feature is that you can only occupy a space once. there are some modifiers to this. Also you have a bomb, but you only get one. and if enemies are present there is only ever one enemy
