How To Play

You control the @ character on the screen. You can move in the four cardinal directions (up, down, left and right) and four diagonal directions (north-east, south-east, north-west, south-west).

For in-game help click on the Help button or press ? while playing.

% represents food that you can pick up and use later. Stepping into food will pick it up automatically.

i is a dose and the player consumes it when stepping on it. It destroys nearby monsters and expands your field of view.

When coming off a dose high, you'll enter into a withdrawal state. In this state exhaustion starts increasing, too much exhaustion and you lose.

You can eat food (or find another dose) to stave off the effects of withdrawal.

When you have an item you can use it will appear in your inventory in the sidebar next to a numeric key. You use it by pressing the corresponding key.

Quick Tips:

  • At the beginning, you can overdose very easily
  • Doses differ in purity, sometimes you come across a weak one and other times it's the bomb
  • You build up tolerance so you'll eventually have to consume more and more doses or move onto the stronger stuff
  • It is possible to win the game


The game is controlled by keyboard. There are three keyboard schemes you can use:

Numpad (recommended)

The Numpad is the simplest control scheme to understand, each key corresponds to its 8-way movement counterpart.

Use 8, 2, 4 and 6 keys to move up, down, left or right.

To move diagonally, use 7, 9, 1 and 3 to move north-west, north-east, south-west and south-east.

If you have a laptop or a keyboard without a numpad the following keyboard schemes are available.

Arrows keys + ctrl/shift

Use your up, down, left and right keys to move in those directions.

To move diagonally, pressing control and left/right means "north" and pressing shift means "south".

So to move north-east you hold control and press right. To go south-west you hold shift and press left.


Use k, j, h and l to move up, down, left or right.

To move diagonally, press y, b, u and n to move north-west, south-west, north-east and south-west.
