WREN

WREN is a one-button endless arcade game where survival means reading the sky and the ground at the same time.

You control a small glowing bird flying through a dark night forest at two heights — HIGH or LOW. Tap or click to switch. The catch: neither height is safe. Stay low and branches block your path. Go high and hawks dive from above. You must read both threats simultaneously and pick the lesser danger — every second, faster and faster.

One input. Two threats. No second chances. Built entirely in HTML5 with no downloads, no installs — play instantly in your browser. Free to play, pay what you want.
