My girlfriend and I enjoyed playing this game a lot. We were both playing at the same time and enjoying competing to see who could reach the end. We couldn't get past the tower. The jumps had to be absolutely perfect in timing and position. Normally I wouldn't have a problem with that; if a game is too hard, it's too hard, but I wish you would have included some sort of jump upgrade in the game.
By the time I had gotten to that level my flash game had been eating a LOT of CPU and RAM and it was causing my game to lag. If my game lags it ruins my ability to predict how far up my character is jumping and at that point the game is impossible because I can't control my character properly. It's not your fault at all. I won't detract my opinion of the game for that, but it's a shame I couldn't see the end. I really liked this game. :(
