Don't let the graphics be the determining factor. This game is all about the puzzles. You move the robot around, picking up and placing items, in order to reach destinations (atoms, and/or the exit). It seems simple when described... but it's not. These are very well thought out puzzles. There is no timer, no penalties, no coins to buy, no ads, and no rush. Just the puzzles. I like that. I also like that this game has a 'back one step' feature. If you get yourself stuck, you do not have to start over on that level. This game also has gamepad support. The screen controls are fine. I just prefer a gamepad. Some of these puzzles, when first viewed, can look simplistic or impossible. When you finally solve a particularly challenging one, you find yourself thinking how clever this really is. You have to try it. Don't look at videos with solutions to see what this is about. It will ruin it for you. If you like a great puzzler, get this. One suggestion for the developer: Offer a free 'demo' version with a few levels so more people will try this.
