I liked the idea
I eventually got into it but, it was too pixil8d and when you jumped too far before stomping on the opponent, you bounce like a mile back (dramatization). This adds a bit of difficulty, which I think some people might like. Also I refreshed this game because when I died I thought my browser glitch-ed or something. Make it clearer that you control the opponent after you die.
this could be a fun game...
I personally don't get the point of multiplayer flash games where both participants have to play on one keyboard (or at very least, in the same area)
if you were to make this game against an NPC, it could be quite fun.
Yeah I suppose that when friends are around, people won't be going to Newgrounds, so the audience for this is a teeny tiny one.
But hey if it would be fun against an NPC, I bet it would be much better against a friend!
