I normally do not like platformer somehow I finished this game. Very well done but I get stuck at 6219562471912 for almost 30 minutes.
hahaha yes 6219562471912 is quite difficult, I reached the same conclusion when I tested it. I left it that way because it is not necessary to go through that room, I thought that people would turn around and try it from the other side XD
What have I just done...
