I'm having the same problem as TheMonkeyman. I'm at the way end and its just a white screen. I can't do anything. I tried reloading, but it just goes back to the white screen.
There's a glitch on 3-3. If you're on the last part and you get a jelly thing stuck on you and try to pick up the ruby, the trophy and the jelly disappears, leaving you stuck on that part until you exit to the map and try again.
I have issues when my character just keeps walking in a direction and I can only change the movement in the other axis. Is this a problem on my side or on the games side? Anyone? cause it really sucks to die halfway between save points.
If you know you're going to fail you can hit the x in the bottom right hand corner to pause the game and then you can hit retry without having to wait for the fail screen to come up.
