Neat! The gameplay is very smooth and fun and I've enjoyed the increasing difficulty and complexity of the levels! I'm definitely gonna get all of those medals ;P
By the way, one thing totally caught me off-guard. I've noticed that in the software section to the left you have "Inkscape" added. Did you only use Inkscape to make this game's art? If yes, then I'm really impressed, I use it on a day to day basis and didn't know you could make full games using it! ;D
