Nice idea :D
As stated by others, the area needs to be bigger or more areas, and there should be a better trick system. as not stated, this game would be alot better with ragdolls when fallen. You cant go wrong with ragdolls....
I cant seem to do very well though.
Overall good idea, if you pusue this plan any further please take heed to my advice, or dont if you feel it is not helpful.
Thanks, Sil.
