lvl 27 should be level 6.. it shows kind of all the basic moves you have to do... why is it rated in hard ? if you can't do it right away then you got there by chance...
Level difficulties are not well balanced, too bad it could have been a very good puzzle game.
+1 here for something giving victory when every dice is on a slot with an even number and all slots have at lest one blank space around... so often in the hard levels to have to finish with back and forth move.
Challenging but not that hard, interesting use of doors feeling even if that is quite hard to see in advance how multiple doors behave and in which state they are. some improvement on this and it would be really great !
CROSS YOUR EYES :) Symmetric one are quite difficult, but i love when it's a duplicate since by crossing eyes you can get all the differences directly. The funny thing is that you get where there is adifference but can't tell the difference since you are seeing the blended images. people you should try :)
well done, especially the blind idea. Bonus or special points with capabilities ( like having a 2 sec no blind preview, or .. ) by the way it really feels like 3D logic and this kind of game, some idea could be shared colored points ? etc i'm sure you can give make your game a must ;) but keep it simple !
