Trees without colliders, cubes not correctly made, wrong texture for grass, rotate is not working well, u should make W-forward,S - back, A and D- rotate camera left/right. Even "walls" are wrong here (u should correct "Y" position)... u could just make mountains instead of them, it would look much better and its easy. Overall... keep learning...
If u repeat trainin where u have 1-2 stars u should lose less energy. Also speed training its really difficult, u need to be really lucky not just fast. Even player who should get pass sometimes cant reach it
