The happy, singing music got annoying for me after a while... My only criticism on the gameplay is that it is very slow at the start - although this isn't really a bad thing I think it would turn some people away from the game. 4.5/5
My only problem is that the game doesn't seem to go back to the title screen at the end (I'm forced to refresh). The keys are fine when you get used to them - surely people can manage using the arrow keys instead of WASD? Although the style of the game resembles Portal, I'll still give it 5/5
Really nice ame. Its funny that the first level turns out to actually be tricky (to get 5 stars in). BTW I think it's good that the walkthrough doesn't show how to get the 5-star ratings - it means that the game can actually be challenging and thus allowing Kongregate to have badges.
