Thank you very much!
We are trying to address the rough start with instructions, videos and gifs.
Also been tinkering with updated start area, I think it feels a bit better now, will keep working on it. Definitely more spectacular...
Build will be updated after voting is over
Regarding frame rate, in new build we picked a few low-hanging fruits of performance optimization, like turning off dense tree colliders, lowering amounts of lights and ratios on particles, etc. Should feel significantly better now.
