I thought it was good game but level 10 was way to hard for me.
i was expected a game more like unfair platformer, this game is more of a "frustration platformer"
had 4 deaths till level 10, then the fun stoped. 124 deaths later i made it to the next level.
I was also getting the problem of some lagging (/slowness).. It did make it hard to play.
Other than that the game seemed to have some potential as a decent action platformer.
It's pretty good, but you should expand on graphics and make a level editor.
pretty easy ! but fun :p
