Here's what I like: if you wish to move the dot (not pushing anything) to any place on the grid, tap that square and it will do the rest. Skips the tedium.
There are 240 levels. I did the first 20, another 40 levels in the middle and the final 20. They go pretty fast and are not very hard. But keep in mind that I've done a few thousand of these types in other games.
Square - Push Square is pretty slick and well done. I'd just prefer to see some very challenging levels.
