Crypto

Crypto is a puzzle game built for NES hardware and playable on modern systems. You're stuck in a crypt and need to work your way out by solving puzzles and avoiding hazards. The game uses a room-by-room structure where you figure out each chamber's logic to progress deeper. You'll collect relics that give you new abilities for tackling later sections. Enemies patrol set patterns rather than hunt you directly. The visual style uses NES-era tile graphics with a dungeon aesthetic. Puzzles lean on spatial reasoning and item placement rather than reflex timing. If you like methodical problem-solving in a constrained retro framework, this delivers that without hand-holding.
