Great game

I have been legally blind since 2010, and due to my limited vision there are very few apps I can play. this game is one of them thanks to the contrasting color graphics and gaming controls. This is worth the download if you enjoy puzzle games as much as I do. There are a few bugs, and my gameplay was erased after I updated, but it’s such a good game that I didn’t even mind it that much. I was going to replay all the levels anyway. all around great game, very fun. if you know somebody who is visually impaired, this is a great game to recommend to them and a great team to recommend to anyone who loves puzzle games. :)
