Strangely enough, this works in Finnish too:

Uida - to swim

Uittaa - to make someone or something swim

Uitattaa - to make someone make someone swim

Uitattattattattattattattattattaa - to make someone make someone make someone … make someone swim

It’s almost as if they are related languages or something.

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.
