A minimalist, creative, hard and cheap plattformer, which combine all the good old features, like triggers, moving and rotating plattforms, spikes, etc. in one big Level and adds a new gameplay element such as the player automatically jumps if he hits the ground. The idea was to remove everything that dont have to be in the game and create a game, made of pure gameplay and level design. So, ingame you have just one big (3.4k blocks long) level with 56 checkpoints to save in it, that will take you for houres to come to the end.
This vid shows you how to use the level editor.
