I think that for the most part Disc Room is a good game. But at a certain point in the game i was not relying only on my skills, but a lot of times a got the feeling that i was just being lucky or unlucky. By the end, i wasnt sure i was playing because i was having fun, but because i wanted to overcome the challenge (a similar sentiment i had when playing Super Meat Boy).

There is a fine line between a fair challenge and frustration. The randomness of the disc spawns and some of their behavior bring Disc Room to the frustrating side. I beat the final boss, but eventually gave up on the game during hard mode.
