Level 25 seems impossible... the door in front of the X opens only in a way that traps the square, no matter what I do... the door below is in the way :(
Pretty cool puzzle game, although I must admit I got so far mostly by luck and less by thinking the puzzles through.
Having played till level 20, I'll give it 4/5 (I'm not giving it a 5 because the controls are a bit oversensitive, which is kind of a biggie if you're playing fast).
To all those who want hints: There is a walkthrough over at freegamesnews.com, and also there is a thread for hints in the forums here at Kongragate. Let's not post hints on this page since EvilDog asked us not to :)
Finally finished... but I required a walkthrough for levels 84 and 86. On 86, it was once more a problem of interpreting the image; I was thinking of things like earring and christmas tree ornament. Also, on level 92 I was a bit stuck because it wouldn't accept the noun, until I tried the adjective. And 96 should perhaps be more general (although I personally got it easily, you should go for the general term). Things to keep in mind for the sequel! :)
About what I was saying below... I just managed to answer nr. 63 and I have to say, some interpretations are way out there.
I still think this game deserves 5 stars for the concept, though.
Small complaint: Sometimes it's more a matter of "name the shape" than "recognize the shape". I was stuck for ages on 62, trying different names for a shape I already knew. Similarly on 59, I had drawn it on paper and was looking at it for some time until it dawned on me what it was supposed to be.
My problem was fixed, I don't know if it was my browser acting up or if someone fixed a bug somewhere...
I'm on level 31 now... I can tell what shape it is but I don't know how to say it :(
Great game! Congrats!
On what Und3rtak3r said: Even though I think he was too harsh in his criticism, he has a point. Very often one ends up clicking the wrong part by mistake, and if you're playing fast this can be irritating. I suggest the addition of a grid, so we can see what we're clicking. It would be best if you could turn it on and off, so you can see the pretty shapes more clearly.
Otherwise, I find the game very enjoyable and relaxing :)
