Wish there were more levels
The logical challenge is real, especially on levels 3 and 4, but then that’s it, unless you redo levels to get a better score…but there is no system for rating one’s score, other than comparison to oneself. In other words, no number of stars, or color of stars, or anything. Very sparse. I’m not sure why anyone would use the sandbox mode, although if more challenges were presented, the sandbox mode would be a place to work on them. Because of the sandbox mode, additional logical challenges could easily be added without having to construct new levels.
