It seems that I found a bug, when I jump in certain area they teleport me for more advance area in game, than I cannot resolve the puzzle. They put me after a river, and I am a robot, I canot pass to return.
EDIT: I finished the game, but I understand now that the bug only appear when you are jumping alot with the mole in your inventory. You can verify it if you want in future make an update. Awesome game \o/
