This game is the sequel to Hard Puzzle, and like the first, it has some purposely underimplemented parts, and lies about its difficulty and even about your goals (or does it?)
I haven't finished it yet, but I've read all the text from decompiling, and I know the last command(s), just not the middle.
In any case, the game has a large number of critters with independent AI and some emergent behavior. It's fun to play around with.
