iC2 by MrCrocodile, is a game where you, a black ball, roll around a large circle avoiding spikes.

Gameplay

You begin as a black ball on a black hollow circle in a pink map. You rotate clockwise. You have one control, which is jumping. You cannot alter the speed of the ball. Death is caused by touching a spike.

The objective is to survive as long as possible, as indicated by the counter in the top right corner. 3 conditions are possible; the addition of extra spikes, the black ball respawning at a different part of the map, and an enlarging/shrinking of the black circle. Sometimes these events can happen together.

There is also a shield entity which floats above the circumference which, when absorbed, creates a temporary shield around the ball, protecting you from the spikes.
