ENTER is not EVERT
So you interact with objects to change the background. Why is the object invisible? Sure when I hit the button it shows a circle, but only if I'm close enough.
When I'm using a controller, there is no way out of the game. Just pause, jump and whatever button changest the scene.
The bushes that I can stand on should look more like blocks, because it looks odd that I can hover in mid air.
The clouds that look like blocks, but aren't blocks shouldn't look like blocks until they are solid.
These are levels, not worlds.
There seems to be a checkpoint system, you should visibly show check points to give players an objective to get to.
After getting to what may or may not be the end, the game just exits or crashes to the desktop? I assume its the end. But the game says there are 22 worlds and I wasn't at world 22.
