I finished the game in an hour or two. Fun, innovative concept. The final level was the hardest for me. Some of the levels feel like the authors just put them together arbitrarily to overwhelm, but there are a good amount of easier "fun" levels which introduce new ways of thinking about things. Unfortunately, the entire game seemed to be made up of either easy/"fun" levels or harder/"overwhelm" levels -- the concepts introduced in the fun levels didn't seem to make it into the normal gameplay. (Or then again, maybe I was just using the new concepts so often I didn't notice!) I was initially angered and almost quit when I thought that the authors weren't letting me know when I could jump down pits without dying. It took me a while to realize that the entire edges had to overlap, rather than just the specific pit I was jumping down. Overall though, it's rare for me to finish a Flash game. So it gets five stars from me!
