Awesome game, in my opinion.
However, I don't think it's worth $15 Dollars at all.
I mean, it's well made, fun, has good sound and cool graphics, but honestly, this isn't worth more than Garry's Mod($10 on Steam), not even by a longshot.
It should definitely be free-to-play, like all the other 8-bit flash platformers out there.
Great game, I love the difficulty, 5/5.
I've now completed all 80 levels of the game, but it says I've only done 33.
I think you should fix this.
Thanks. =]
