- Walk around with WASD or the arrow keys - Shoot with the spacebar - Bring your mouse to the bottom left corner of the screen to bring up upgrades, click on the colorful box to spend XP on upgrades - Shoot enemies to get XP - If you touch an enemy, you will go into a geometry problem and lose 10 health, unless you have defense. If you get the problem right you get 15 XP and will regain the 10 health you lost.
This was for a project in geometry
