Pros.
-Simple and well used platform phisis.
-Cool puzzles. You explored very well the possibilities of the 'splitting' ability.
-Single but enjoyable music.
But there are a few bugs:
-There was a screen glitch when one my clone died to the last drill, on the last stage, before the end.
-The big crates can be pushed a pixel with a single clone if you run, jump and collide with one of the sides. Thus, with patience, avoiding having to get 2 or more copies to pull it.
Very catching game.
8/10.
