Thanks a lot for playing.
It was intended to have difficult challenges in the game, so as to not beat it in one of the first tries, but I can agree with you that maybe I made them too difficult.
And regarding DISC's appearance, you could say that he is a Disc when talking about his personality, and apart from that, my idea was just to name him DISC (which is an acronym, like EVIL, which is also one), not to give him a literal Disc body (Although that could be fun to explore).
