Mind Puzzle

It's a good concept, and similar to one I heard about very recently that's currently in development by someone else (it's called BlackWhite and he'll be charging $10 for it, apparently). I agree with the other suggestions about the screen being bigger and the player being identifiable, and I would add that after you've won a level, when you go back to the level-select screen the next level should be the one selected, not level 1.

Unique and fun game! 4/5!

Excellent Implementation, bad concept.

The concept of changing colour needs some work. It's a rather boring concept to just change colour to get through certain blocks, it's not really strategically deep. However, you implementation, the smoothness of the game is very well created. Kudos.

I'd recommend playing with the idea of colour and the dynamics of the blocks. Maybe there are blocks you can move, but only if your the same colour, maybe you can take on any colour of the rainbow, and you can combine colours to make others (so your red and you walk on to a yellow changer and now your orange).

Cool game bro! :)

Remake...Great!
One more idea might be to make the little block that you can move be identified in some kind of way. A dot or something because sometimes you actually can forget where the square you can move is. Just a thought.
Good Luck on your project.
