Eh. This game wasn't exciting or exhilarating. Not even for me, when I play mostly puzzle and logic games. I like the concept, but there should be more punishment for not using all of the colors on the board. In fact, if you were really ambitious, you would make it so you could only pass through the door if all colors would be used. Gameplay-wise, it felt a tad tedious, especially when having to constantly move back-and-forth, chasing down the colors when the solutions to most of the levels were pretty obvious. I played for about half an hour and nearly completed about 70% of the playable game. I wasn't really too impressed overall. I wouldn't say that I wasted my time, however, as it was just interesting enough to make me play for a good bit of time.
I feel like if you made the movement a little more fluid, increased the difficulty a bit, and added some kind of reward for full completion of a stage (if that's even possible for all of them) and/or some kind of punishment for not full completion (I don't know, perhaps a score keeper or something of the sort?), then I feel as if the game would be a little more engaging.
Not a bad game at all, I just feel as though there was something missing. I hope my review helps.
Good job,
