You are a tomb raider deep inside a forgotten ruin.
Tap a square next to you (or use the arrows / WASD) to move.
Push stone crates out of the way — they can fill pits.
Recover the gems along the route.
Grab keys to open sealed doors; pressure plates open them too.
Slip out through the exit doorway.
