Good game but I noticed some big bugs.
1. In difficulty, Cloud/Normal and Ninja/Unbeatable? are the same set up and in playing them, there seems to be no apparent difficulty difference. Considering I've only beaten each of those stages once and I've beaten Red Dragon/Hard like 10 times, I figure the dev mixed up which level to load with Cloud and selecting it triggers the Ninja difficulty anyway.
2. There were a few times levels loaded with unbeatable distributions of tiles (i.e. they had three matching tiles stacked on top of each other making it unable to complete).
Otherwise, fun game!
I've loved this game for years. Unfortunately, it was more fun to play when the site wasn't bombarded with a ton of ads. Now it's a lot more ads and very little game. I can't play the game without updating Adobe FP...yet, I was still able to sit through the ad. Go figure. Game I LOVE; but all the hassles trying to play it just aren't worth it.
