I like your effort but Sokoban is such a popular game that you can play it for free for days. I don't think that allot of people would pay to just play it. Your second idea might work better but you have to create a social interaction and add some more flavor in the game. Maybe you can get some ideas from Cundycrush such as: - Preselect the levels and create a path that the user can follow, cartunish graphics and a map like path. - Add new elements in the game. Magnetic boxes, explosive boxes that can be pushed one x times, plant boxes that must be moved every x moves, etc - Add items that counter do some of the previous mentioned traps. Unroot a box, reset explocive box etc. - Have a way to win these items, fortune wheel, fruit slots, etc - Microtransactions for these items and for passing a level. - social interaction, share a facebook, compete facebook friends - Work together with a graphic designer, make it fun to watch and to play
