The buggy-ness is completely my fault, I am still not very well versed in the engine and because of that my implementation of collision is not the best either, I have been getting incrementally better at it with each successive game, but there is still clearly a lot of room for improvement as it is sub-par at best. You cannot just complete the stage blindly either as I made it so that the player must be near the light-switch in order to click it. I will most likely come back to this idea in the future when I am more well-versed in the game engine and can properly implement collision with the projectile. Thank you for your feedback and I hope you have a nice day!
