Misses the whole point in video gaming.
You've missed a few important rules when making games.
When you're making a game that is hard it is of outmost importance that the controls are perfect. That's what made Super Mario such a great game, you had perfect control over Mario. This games controls are very stiff and barely working. Unless you run all the time there is no way you possibly can dodge an enemy or jump from one platform to the next, so basically why the character isn't running at all times is beyond me.
Also after having died a few times (just having played like 5 mins) an ad pops up. Advertisements... yay? No, fuck advertisements. Plus after having viewed the ad the whole game started acting up and everything beyond the first few crabs was just entirely blue and I couldn't see what I was doing.
Seems like you tried to make a decent Super Mario or I Want To Be The Guy-like game, but you failed because for such a game to exist the controls have to be perfect - and this one honestly ain't even much fun to play nor are the challenges spectacular. I die trying to jump half a metre over a fucking hedgehod for christs sake, that ain't cool.
