The game was certainly addictive like other difficult platformers. I do agree with the other commenter about the instant reset (perhaps when you die, the camera stays put, and the game tells you to click R to reset instead of instant reset). Also omg the spikes around the 4th level end are way too close to get it done. Some spacing around the danger in the level design would keep it difficult albeit with more rewarding deaths (ie dying due to player skill rather than difficulty itself)
