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.
