It's an interesting take on the hidden platforms mechanic, that many others have also attempted. However, the movement of the character is very floaty and there are no in air controls; making it quite difficult to do precise platforming. It's also not possible to shoot while in the air. The ground is only revealed when you land on it, but it would be nice if this also happened when you walk on to it. Perhaps you can also add some ambience to complete the atmosphere of the game.
I wasn't able to make the jump pictured below. It seems like others are also struggling with it.
