I don't really mind that grooh looks like totoro.. It's a cute character and I like it, the art is the best part of the game, that's the reason I was drawn to the game, finally picked it up, it's very cute and feels more unique then I thought it'd be judging by the gameplay videos.
Haven't played much of it yet but so far it seems cute and unique.. I love the color changing elements too, but the gameplay is a little stale..kinda like a match 3 I guess..I haven't seen too much of a challenge yet but I've only played 5 levels , I'll play it more later and see if it gets more challenging..it looks like you complete the level no matter how many moves you make so there's no real challenge unless your going for gold medals but even then it's quite easy..needs some sort of extra gameplay element to make it challenging..maybe later more will come..
But it's very adorable and fun so far..so I'm happy with the purchase
