Difficulty and hints – ERASE - coloring puzzle game Review

So the game in fun overall but it does have some issues. First of all the levels don't really get hard like some are definitely harder but then the next one will be super easy and you won't get a hard one for a while. Second when you need hints they cost 200 and the first few times I watched a ad I got 200 or 150 now all I get is 50 over and over and I don't mind getting 50 once in a while but every time it's gets annoying because it's a lot of ads.
