I typically don’t make a habit out of phone games, but this one was the exception for me. It’s definitely a “puzzle” genre game, and undoubtedly challenging at times, but it’s really fun for two reasons IMO: • Like most free games, there are adds, but this one wasn’t nearly as frustrating and in your face, and there is nothing you need to purchase in order enhance your experience, or to keep playing. • It never became so difficult that I wanted to delete it or stop playing. The level of difficulty keeps you perfectly at the edge of wanting to continue and push on as you make better attempts to solve the levels. Honestly, the only downside is how addictive it is. 🤦🏻♂️ there was one night where I couldn’t sleep, I ended up playing until I had about an hour and 1/2 before work the next day. I’d like to take the opportunity to thank the developers of this app for providing a game that is actually free and fun. I beat it and can’t wait for new levels to be released… Thank you!
