Balloons, gifts, squares and a lot of jumping combined with a lot of thinking. This is how one well done game called 100th can be described. I must admit this piece is no easy thing and I had to watch hint many times. You control a square or a small guy who tries to get to his goal and collects gifts. His best friend is a balloon and with is many amazing things can be done. The game will teach you them but the right use is up to you.
