Yeah, so the randomness was my fault, me and my friend made the game together and he went to bed at like 3 am the day it was due and I finished a few things before submitting it. We then later realized the randomness was because we had two of the same script on the character with different values. So it was causing him to behave very strangely and sometimes flying with double the force, which caused him to launch way further somethings. So yes it felt random because it was random, not intentionally but by accident, thanks for playing the game though!
