This game has 3 special features I built to be intuitive and easily learnable. Instruction guides for mini-games can otherwise disrupt a seamless UX.
- Clicking further away from the ship makes the bullets travel faster, learned through quick trial and error as every click reinforces this feature
- Force fields on the protected asteroids, learned visually by drawing the well-explored illustration of blue force-field rings
- Freezing bullets when ship is hit, learned visually by design of frozen ship and again by trial and error as every click reinforces the inability to shoot
I successfully achieved intuitive design. Test users immediately understood the force-field rings and the frozen-ship design, and they learned how the bullets worked almost instantly due to how frequently they clicked to shoot aliens.
