Boxup was my first published Android app. I made this little game in 2010. It’s an Android clone of a free puzzle game I found on the web.
Basically, the object is to move your man around and push the smallest box inside the biggest box. It’s kind of like Sokoban with a few differences. There are obstacles to impede you and some different sized boxes to help you. The first few levels are quite easy, but it gets rapidly more difficult as you progress. I’ve duplicated the original levels, but I’ve only managed to finish 6 of them. Levels 7 – 14 are crazy difficult!
Anyway, it’s not very popular, so I’m not maintaining or enhancing it.
