Really fun! Unfortunately, it doesn't save your progress.

I remember playing Sokoban in my childhood on windows 95. It was a long game of 50 levels. Took me many days stretched over several months to complete it. I liked it but I wished that it would have some new elements. Many puzzle games today feature portals, so I was thinking it would work nice in Sokoban too. And finally someone made Sokoban with portals! Great!

Fullscreen is also nice. My childhood Sokoban didn't have such a feature.

Now I completed these 32 levels in just two or three hours. Very quickly compared to my cildhood skills. I must have become really good at puzzle solving over the years. :D. I give this 5 stars for Nostalgia reasons. If you make any more Sokoban games with new elements I will give them a good score too. Just don't make them too short. 32 levels is really the bare minimum.

You get 5 stars, because I can't think of anything to improve on the game except for more content.
Excellent design implementation. Graphics and sounds look match well.

Very nice! I love the game. But it was too small! I finished it way too quick, please add more levels!

Great little game! Excellent work! Please, make more levels and incredible games like that.
