I know this game—I love this game❤️‼️

My favorite rendition of this type of puzzle has long been Mgaon’s Lunchtime, for the adorable kawaii. This contender’s execution is more sophisticated, and expertly rendered. Like Lunchtime, I don’t like the fact that Tap’s sound FX and music controls aren’t separate settings. Unlike Lunchtime, Tap to ON has lovely, tranquil music and decent FX (with the exception of the “clear” whistle. Ugh.).

Tap also brings a playing board that goes beyond 3x3, as well as higher-function tiles (bulbs).

Ads are minimal and unobtrusive, and can be eliminated with any purchase of more levels. (Always support your appreciated apps with cash, if you can!)

Passionate, ethical developer. Will buy more from them 💯💮🉐

Great puzzle

So far it's great to keep my brain moving and thinking out of the box. Slight down-rating because some of the colors are a bit too dark for me. Others probably enjoy it fine, though.

New favorite game

I love the concept. I wish there was a timer to give hints after so many hours of gameplay in addition to purchasing, similar to Doors and Rooms. The "skins" are more difficult to read than the default. Some levels can be beat with fewer moves than the "best" number.
