I personally think this is a great game, but if you could fix some things about it, it would help me and others like this game more.
First, the lag. Before an ad, after an ad, when I start a level, or when I finish one, it lags. If I had to compare it to something, it would be like Minecraft lag right before it crashes, only the game doesn’t crash.
Second, the ads. I don’t mind the occasional ad, but like another reviewer said, they come up to often. If it was more banner ads instead of game disrupting ads, I would like that much more.
If you could try to fix those problems, it would really help my gameplay. If you can’t fix the problem/s right away, or just start working on it, I will still play your game because it is good. But if you could fix that, myself and others would appreciate it.
