It's an ok game. The level design is good at first glance, but the spikes right before the key come up way too frequently and the save points are few and far between, and don't save if you've got the key or not. The jump is way too floaty to be any accurate, and the lack of a shadow beneath you makes it very hard to gauge where you will land, especially after that super jump pad. The last stretch of the game being so difficult and essentially save-point-less made me quit before I could reach the end. Oh and you can control the player with a controller, but not the camera. It would be very fun if the camera controls were mapped to the right stick on the controller.
There's a fun game hiding under these problems, though
