It's a cool idea. You can kind of tell where the groups of obstacles repeat though. Perhaps if you made more it would give it more of a "random effect". Nice work, and good luck in the contest! 4/5
Once again, thanks for the constructive criticism everyone! (This site is very good for that!) I'm planning to add a few more blocks (special ones), as well as jumping to a future version of the game. Once again, I'm just glad you're all enjoying it.
Thank you for your suggestion Bballdwade03! I appreciate it. I'm planning to look into a way to fix the lagging, but I'm glad that you still enjoy it! (It's my first game.)
