Oh wow. I thought this was just a fun little tribute to wolf3d. After two days and six hours of playing I now understand how wrong I was. After a few levels it turns out to be so much more, and just keeps getting better.

I just gave this a go not expecting much. Man is it fun! And works great on the deck too! Playing with a controller makes it extra hard, but then again the originals were hard too and had even worse controls, so it fits well.

NandGame is a browser puzzle game, where you start of by building basic logic gates from relays and progress from there all the way trough processor design to compiling high-level languages. It does not hold your hand too much, but the invidual puzzles progress so incrementally, it feels almost magical how easily you learn to build computers and compilers.
