In terms of safety, this project does not have anything dangerous involved. None of our materials should cause any serious injuries while playing the game. There are minor risks of skin inflammation from extended exposure to very strong IR light (our LEDs do not emit strong IR light), so even when the risk posed by a small LED is infinitesimally low, it may be advised to wear lightweight gloves or have some other barrier between the skin and the LED.

While the game can largely only be tested through qualitative forms, completing the demo with multiple players who were unfamiliar with the game affirmed the quality of the design. The controller is designed to be simple and intuitive (avatar motion mirrors hand motion) so that the player can improve at the game quickly and so that the game design is accessible to those who would benefit from the control scheme the most. The final hardware test video shows the immediate responsiveness of the controller to a block in the light beam, and the final demo shows the quick refresh rate of the display with minimum hesitation and flickering that ensures the game runs smoothly.
