Happy Glass

It's the basis of a good game, but has some of the most aggressive and invasive ads of anything I've played (be sure to play on airplane mode), and the levels are insultingly trivial. I played almost 50 of them, hoping they'd eventually grow challenging, but 90% were solved by a straight line or an L. If you took out the ads, this game would probably be great for very young children (perhaps 3-7 y.o), but if you're older than that and looking for a challenge, look elsewhere.

Very addicting, and really makes you think, but reward system is ridiculously cheap. The game already makes you watch videos between boards, but to get a hint or any coins, you have to watch another 30 second (approx.) video. If you're watching the video for coins, it's a "free" spin after the video. which doesn't usually reward much considering any water colors, cup designs, or pens in the shop are 1000 coins plus. Coins should be awarded for passing boards, that simple. Likely uninstalling.

Quite addicting and not so difficult to where I need to use hints every time, thus creating a need to spend in-game currency, thus mitigating the need to spend actual currency. Level 68 and only needed to use one hint. However, I can't give this a 5-star rating due to the fact that I can't see where I'm drawing the line. Some of the levels require precision, which I eventually get after having to retry way too many times. A lot of them I could've got the first time, had I been able to see where my line was. Please make the drawing point away from my thumb placement. Other than that, great game!
