Added Particles

I added particles when the cubes strike the platform. I used Unity Particle System to make them, obviously. It was my first time making particles and actually using them. It required some time and effort. Yes, Brackeys is awesome, as always. The content on his channel which is years old, is still amazing. Anyway, They work alright, not the best, I am still not good in making them (it is so huge, no one can really be perfect in it). It was not that hard to add particles but they did made a big visual difference. I will try to fix bugs and meet you in the next devlog!
