Firstly,
Great Work!
it takes a lot of work to make even a small game, so be proud of your efforts.
Here are some pointers to help you improve your games in the future.
Your light beam mechanic doesnt initially stand out to the player. Some ways to make it stand out could be to pan the camera back to make the light more central, making the light brighter, increasing the initial sound of the light. (or do a little of them all)
Finally,
Adding some kind of exit function is always a nice feature. Even if the game is only a MVP or DEMO.
