Tilebug? I did test it and I didn't notice what you're talking about, though everyone keeps saying the same thing. If you mean the part with the small opening, you have to be running and jump to get through it. If you're talking about something relating to eye candy, my slight colorblindness might have something to do with it.

The roll rock part I made my last edit, and I didn't have the time to finish it. (There isn't even a real playable path leading to it yet.) I plan on improving it in the future, or if anyone else wants to improve it feel free as well.
