from this bundle, I very strongly recommend playing
a monster's expedition.
one of the best puzzle games I've ever played and probably THE best at hiding secret bonus solutions to puzzles right under your nose. basically every single puzzle in the game is actually two (or 3, or 4) puzzles at once
edit: in case this sounds too intimidating, I think the game is quite approachable for a basic clear and finding some of the bonus areas. 100%ing it will probably be 30+ hours though
THIS IS WHAT I HATE A BOUT EVREY WEBSITE!! THERES SO MUCH PEOPLE READING AND POSTING STUIPED STUFF
