If you hit a level were you can warp though a level warp though the points then go though the warp then you can soft lock the game becuase you cant move
I'm curious, can you tell on which world/level this happened? I have put contingencies in place for this.
It happened for me on chapter 1, where there was a warp, but the lock wasn't opened yet, so I had to close and reopen the program.
