nice game! it's amazing how hard a 4x4 grid can be with these mechanics.
Thanks for playing! Yes... I was surprised also how much depth was possible on 4x4. Exhaustive computer search can sometimes yield some surprises.
ah, it's computer generated. i was wondering how a human brain could come up with this. nevertheless, this was fun to play. i'm giving up on the last 6 or so levels for now, but i'll return once i have a break!
