Jaja you got me even after the first level with the chasing guys, those little bastards are hard to avoid, an earlier check point on those screens will be nice, also found a glitch which got me back to the beginning of the level (in the screen where the exit is, you can walk all the way back to previous screen which will result in a teleport to the beginning, see screenshot).
The next level was too hard for me, but I had a good time !
