pretty good actually
At first glance i thought "man, this sure is going to suck". After playing for a while however the game started to get pretty fun and i changed my mind. A decent platformer with a really catchy tune kept me playing through the whole game.
I do think however that you could've done the levels more interesting when it comes to the backgrunds. I'm not saying there needs be advance graphics or anything but something different than just "gray" would've added some enjoyment.
The medals could've also consisted of something a little more exciting, like "beat the whole game without dying", "get through the whole game in X amount of time" and so on...
But you did allright with this, it's not bad at all.
Not bad :)
I did experience lag whenever there were moving objects on the screen.
I liked the music, although Guitar Pro / Fruity Loops guitars sound dumb :P
Easy enough but controls pissed me off.
Some of the levels could be a little bit of a hassle but 75% i beat on my first try. The only thing that ever killed me was that sometimes when you pressed jump it would automatically waste your double jump. This happened to me more times then i could count. You might want to check it out cause it is quite the annoyance. It was decent enough for a simple platformer, but really it left much to be desired.
I will admit that i only played a few levels. From what i see the game is an enjoyable platformer with decent controls and music... i would suggest adding and extra gimmick or ability to the game to add a new dimension or perhaps enemies to spice up the scenery.
Its pretty decent platformer, and it will keep you playing for the 20 levels. I liked the music - what was it? One or 2 of the levels are a little tricky but other than that its a fairly easy game.
