double click to start. click to place your player on the map and use wasd to move. evade the storm to keep your health meter high. you can swim, but don't go onto the side bars that are solid black, you die instantly. stay within the storm safe zone (inside purple circle) or your health meter (top left) will run low. if it reaches 0, you die. storm damage per tick (half second) is shown at top right. if you can't see yourself, press space and your character will flash. once game is over, you have to click start again to begin another.
fun fact: there used to be a bug where walking into tilted towers would kill you.
