We made a modification of the famous game Sokoban. It's called Boxes-X Extreme and you can download it on mobile phones / tablets and PCs. We have tried what the hardest difficulty. Includes over 200 new levels! Anyway relax. No action, no time, no stress. The game is FREE. Written in Basic AGK2 (http://www.appgamekit.com/). I hope, you will like it. Thank you for your support and any comments!
Nice! I just played it a bit under Windows. Gameplay works fine. (maybe some mouse click repeat on the level selector increment/decrement would be welcome) And the name is appropriate : Levels are indeed extreme!!
