Up Left Ou‪t‬ 4+

Like all of this developer's puzzle apps, Up Left Out, delivers on the promise of nicely challenging, well-designed minimalist puzzles.

If you are a puzzle fan, get all of the great apps by this developer. Just be prepared for the puzzles to run out well before you are ready for them to. Even with the limited number of puzzles the apps are well worth the price. Great for a quick diversion.

Good puzzle game in the vein of sokoban, though with more complicated switching mechanisms. The levels do a good job of introducing new mechanics and training you on them. It's a good bite size game for the price, with a variety of levels.

A handful of the levels can get you stuck in a configuration loop for a while until you realize the exact sequence to get everything lined up.

My only UI frustration is I couldn't find an easy reset button, even though it was technically impossible to get stuck on a level it was sometimes easier to start over. The workaround is to go back a level and then forward.

This is like an old 15 slider puzzle, but with increasing challenges being thrown at you. I love that you just have to figure it out as you go, and that you can never really get stuck. You just have to keep trying until you figure it out. The variations on the puzzles are really clever. Great, relaxing, and challenging, with a straightforward and simple design.
