I know I am new round here, but I'm just trying to get people playing, so i've got someone to indirectly play with 
Few Ideas for challenges we could do against eachother:
Already got a speed run level thread
Speed Run Bosses
Best Level Scoring Challenge ranked in this order: (Difficulty, No Items, No Damage, Score) Which stops people from grinding enemies since a player with a 500k score and No damage beats a player with damage and a score of 200 million.
I have just reinstalled fraps and Vegas set it up so am quite up for getting some stuff on the go, even if you are even worse at the game than I am (unlikely) I think this could be fun if we get a half a dozen people or so.
