Why would you post this incomplete thing as a game? For a start, sort out the collision detection!
If you had called this a "beta" I might have given you 2/5 if I had been generous but I think it's a kindness to give you 1/5!
The "you can't play because this game is full but we are so crap that you will have to reload the whole game to go back to lobby to try entering a nearly empty room to receive this message again" routine is REALLY BEGINNING TO WIND ME UP
First up, don't bother playing this unless you register... for me that alone kills it... the game is repetitive and dull and is glitched to high heaven. Forget this one
What would make this game a complete winner would be level editors so you can challenge your friends... and if there were a high-score-table like system for the hardest levels... but you would have to succeed at your own level to allow it to be accepted.
990 is my best but I think it's because I'm using a pad... I'll get the high score with a mouse... hint... you need to find *8* differences every time to get a top score - but you have to click the last three in rapid succession!
Ridiculously easy, especially if you cheat. Cheat? How? Well, just go cross-eyed until the two images overlap and then hold it there... your brain will spot the differences for you by showing them up as almost "glowing"... this game is great practice for the games machines in pubs where you can actually earn real money :)
Oh my, how did Kongregate allow this up? I thought that silly shape was the preloader but oh no, that is the game. No menu, no instructions, no music, no enemies, no points, no point!
Oh and the third secret is a link to a similar brain twisting game :)
I think this game is fairly good (although not hard enough for my liking) and rate it 5/5 because I want to see more like it :)
LOL - level 33 is a lot easier than you might think... if you want a hint (I assume that you have all worked out how to think backwards from the end) - concentrate on the two blocks in the middle :P
Shame this game doesn't work in Google Chrome... just get "[7] setup has failed: loader bypassed"... but it does work in Firefox and a standard browser that I won't do the honour of mentioning.
