To Leave is a little odd. You're this guy, and there's this flying door. You grab the door and try to escape but the door is fragile and breaks if it hits almost anything.
Fortunately, there are a fair number of checkpoints so you don't always have to start back at the beginning.
The game starts out hard and gets mindblowingly difficult from there. You'll need strategic thinking and quick thumbs to beat it.
If you have 2 minutes, you can get to know all about this game from one of its Ecuadorian creators.
