Thanks for an in-depth feedback! I did the entire level design on the last day so I was rushing to get it done. I'm planning to update the right path at least since the key is hidden behind an unconventional slope that could confuse some people. Probably going to also implement a load screen for the performance problem you mentioned, I didn't seem to have any problem performance wise on my end but it'll help others at least. And yeah, the rocks didn't export to Unity as I would've liked with the deadline close, so I'm redoing the rock model entirely after. As for the smooth shading, I did turn on smooth shading up to a certain angle, I didn't want it to look too smooth but I'll play around with it some more as well as the materials. Thanks again for such an expansive feedback!
