Um, ok. 615 and only because I started to play with my eyes closed and I finally fell. Only 7 constantly repeating platforms. I give you props just for creating the game but that's about all I can give you. Good first attempt though.
500k @ 9:33, 1 mil @ 13:24. At this rate, in 24 hours, I would have a combo of 11,220,779,220. That's a lot of turtle shell destroying. Why do I need to hit that many turtles?
OK. You did pretty good with the programing but the idea is completely unoriginal. Anyone who plays right away knows it is a Mario knockoff. I just wish people would use their programming skills to come up with new ideas for games instead of just recreating what has already been done who knows how many times. Nonetheless, I will give you 3/5, mostly because of absolutely nothing is original.
I was enjoying myself then all of a sudden it crashes on me. I was just starting to have a nice build up. I believe that it was the turbo elevator shaft that did it. After the time spent on this game, then the crash, I can't give it a high rating. If there was no crash it would have a minimum of 4, possibly a 5 from me.
