Original post: Not a bad game by any means, I like the concept, but there are two big problems:
There are way too many ads (I mean 1 ad every 10 levels? It doesn't seem bad but...), and most of the levels can be beaten in 4-6 seconds. Seriously, I'm on level 110, and I have yet to have a level take me longer than 23 seconds. Most of the levels only took me 5 seconds to beat. I do appreciate the concept very much, but I wish it were harder.
The thing is, I also like how fast the levels go by. Normally this would save the game, but the ads ruin it because you're getting a 30-40 second ad roughly every 40 seconds...
I suppose it could work, but this game is not for everyone. I'll probably keep it downloaded for at least a while, but I'm sure it's to going to get boring very quickly with how simple the levels are.
Edit: So I've been playing this game a lot, and guess what? On level 170, the board expands, and the game actually has an alright level of difficulty. It's still only taking me about 15 seconds to solve the levels, but at least I'm being challenged a little now. My rating for this game has gone up one star because I'm enjoying it a lot more now! I just wish you could reach the harder levels more quickly :/
