The most annoying level

[Maxpphire]

Sonic 2006. The entire game.
(I still enjoy the game because it's entertainingly bad, but that doesn't stop it from sending you into a blind rage out of sheer annoyance.)

Oh, and Sonic Heroes.
The pinball table.
The lava tower.
Actually, yeah, the whole game just plain sucked ass.

I liked sonic heros better then sonic 2006, not gonna lie although Heros does have it's issues. those fucking turtles man.

All of Harvest moon Saving the homeland, the last dungeon in Dark Cloud 1 is pretty annoying, thats all i can think of right now.
