The controls are really good compared to other games on the same genre.
5/5, love it.
I would also LOVE a multiplayer version (think about platform racing)
It's sponsored by kongregate, they already knew this game was amazing and when it was going to be release, that's why it is frontpaged without a score.
So, if this was exaclty the same game, but without the ADDITIONAL paying content that IS NOT gonna give other players ANY advantage over you, you would play it?
Stop crying, making flash games is not cheap and is not easy. You should be happy that this game has a lot of good content for free, instead of blaming the small paying one.
