I don’t play these type of games for the challenge, the mini challenges, the “gifts” or “treasures” - I play them because I love the process of the game. For some games, it’s putting things in order, or eliminating pieces efficiently or just moving toward an achievable end goal. Most games start out quite simple, become more enjoyable - then on to impossible to achieve - or at least impossible without purchasing tools. I play several of this producer’s games & each have this core premise that I enjoy. Yes, tools are available, with ads, but they are short & soundless (with the exception of one game but I will address that directly on that review site) and, I might add - I have found other great games thru them. That’s it. Download & enjoy.
