Brace yourself for adventure, absurdity, and pumpkins.
Mentula Macanus is an absurdist epic that requires extensive mapping and saving, can be frustrating and sparsely implemented at times, but ultimately never fails to delight your inner highbrow with the ridiculous and paradoxical.
Puzzles and story are somewhat linear; the real meat is in its brilliant black humor and totally unexpected moments of profundity. The most rewarding moments leave you truly flabbergasted by obscure references that you didn't think anyone else could possibly understand. Not many games have made me laugh out loud, but this one did.
Play this for its humor, not its puzzles; take your time with it and allow it to exercise your patience; and above all don't take it seriously - you will be richly rewarded.
