There should be a game were 2 players compete to survive. It is a challenge were many things like spikes are heading toward you and you have to dodge them. Players who win get points, players who loose get points taken away and the more points you get the more abillities your person gets.
sounds like pretty much every online game i ever played exept for the 'spikes coming towards you' part and if you're talking about flash games i would say it's impossible to make since there have to be 2 players and you have to dodge spikes and stuff whitch is too much for a flash game to take on maybe 10 years later
i came up with what i thought would be the coolest game idea ever but i keep getting stuck like first i couldnt think of what next then i got really lazy...REALLY lazy. it was about colonizing mars and killing aliens and terrorists. basically i had an outline in my head but never really wrote it down
