Sullen

Sullen is a fast-paced platformer set inside a circle. You control a small pentagon, dodging, jumping and shooting through levels while the Sullen Eye relentlessly attacks. Your goal is to survive every level and defeat it.

Levels and survival

Survive a stage for 30 seconds to advance to the next one. Completing two stages grants a checkpoint; if you die, you return to the previous checkpoint. You can use checkpoints 4 times per attempt.
