How to play

Press Play to load the game. It runs in this page — there is nothing to download and no account to create. It is built for a tall screen, so it works well on a phone held upright. Most browser games explain their controls on the first screen; if this one uses the keyboard, the arrow keys, WASD and the spacebar are the usual starting points, and touch devices are tap and swipe.
