Thanks for playing!!
Environment wise, ye I could have added more. First time using Unity Terrain system, so I just painted the same old texture everywhere lol. I will probably add more gimmick, enemy types and levels, when i have more time.
UI wise, like you said. Just a little bit pressed for time :))
For the weird camera behaviour, I think it would be the Cinemachine Collider component working with the trees. I will fix it or adjust the cinematography.
Thanks for your honest feedback, much appreciated!
