I'm surprised that the Sokoban's download user is steadily increasing.
And feel sort of guilty that I didn't make the game more perfectly.
The popup window is now broken, also you can find the character jumping to diagonal direction when you playing in stage.
I don't know why he moving like that.
More critical I reported that one of stage (Maybe in between 50~60) there one less goal point! But fortunately, It doesn't matter of going to next level.
I think I can optimize and fix the broken popup window.
Soon, I'will be update Socoban Original.
Thanks for your playing!
