You are a box. There are 20 levels. The source code for box can be found at https://github.com/pommicket/box. You can also find more information there, such as the licenses for the code and assets.

The music is a co-production of me, Leo Tenenbaum, and Alex Tenenbaum; everything else is my own work.

This game was created using the Go programming language and SDL (+ SDL2_mixer), specifically these SDL2 Go bindings.
