Thrum

The screen is black. Somewhere in the dark is an exit, and between you and it are walls and traps you can't see. Put your finger down at the bottom edge and drag. Your phone tells you the rest.

A clean run to the exit, the path drawn over the revealed map

How you feel the dark

A hum grows stronger the closer your finger gets to a hazard: dull for a wall, crisp for a trap. A beat quickens as you close in on the exit. Lift your finger or touch a trap and the run is over. Reach the exit and the hidden map lights up, with your path drawn across it. You can play it with your eyes closed.

Can't feel anything? Thrum needs an iPhone with haptics; check that vibration is on in Settings → Sounds & Haptics. Found a bug or a level that seems unfair? Email hello@sharkedup.dev.
