I know that the levels aren't that good, (except the Spring Madness and the Pushing Madness) but the first one is highly based on Sonic Heroes special stages, and i wasn't expecting it to be very long, like the ones of the game, so i made ot get all rings without falling nor getting hit. And for what i'm seeing, Knuckles' path is looking like the same as Sonic's, but harder and with more hazards (also upside-down). The paths in the last special stage look hard, but speed is everything. Once the path is complete, i'll release the wad as 'Levels'. And i'm also enjoying to make the upside-down track with the torches to guide the player.
