easy
Undersea exploration is the point
Subnautica · Endless Ocean · ABZU · Beyond Blue
medium
Developed by Simogo
Year Walk · Device 6 · The Sailor's Dream · Bumpy Road
hard
The crisis is handled through calls or radio
Keep Talking and Nobody Explodes · Radio Commander · 911 Operator · Alt-Frequencies
These games take away face-to-face control and make communication the real problem. You are dispatching, relaying, or piecing together voices under pressure, so the tension lives in the line itself.
tricky
The map is a hands-on tool, not just a guide
Miasmata · Carto · Strange Horticulture · The Legend of Zelda: Phantom Hourglass
These games refuse to leave the map in the corner. You triangulate it, rearrange it, scribble on it, or treat it like the puzzle board itself, so orientation becomes part of play.
