Let me start by saying I'm old by steam standards. I remember drooling over pong, Zork and coding my own games in from magazines ... yep for those of you under 40 this was how we got games. I don't have twitch speed and I need controls to be accurate. Keep that in mind with my review.
Tons of levels
Controls are ... not accurate to a point of rage quit
Debate on if achieves are working
After 30 min it's boring, unless this is really your type of game
OK there has been some comparisons to super meat boy. I think that's not fair. SMB is a great example of the genre. This is, if the controls get fixed, an adequate example at best (sucks with the current controls). if your looking for SMB, go play that. If you want to try a game in that genre, with control issues, grab this one (on sale)
6/10 (+2 soundtrack, -1 price, -3 controls) = 4/10
Get this game at 75% if you have super twitch speed, 90% off if your a normal human, 100% off if your old like me.
