Cellbound is a fully-functional spreadsheet engine with a logic puzzle game built on top.

Spreadsheet cells support standard mathematical expressions and function calls, as well as references to individual cells and ranges of cells. Cell references use R1C1 reference style notation.

Cellbound was built for the Langjam Gamejam in late 2025. More levels continue to be added.

Source code (with level solutions and SPOILERS) is available here: https://github.com/jstrieb/cellbound

The source code appears to be private (I got a 404). Could you make it public?
