A gem path requiring a gem from the very same level is interesting, and something not seen in other Crash games. However, the design of that gem path has bonus round, not gem path, written all over it. I would move it to another level and make it the bonus round, and create a more interesting gem path with enemies for this level.
Thanks for the feedback :) I agree with you, the gem path is a bit lifeless. I think another forest area would actually be more appropriate. I'll definitely think about it :)
The gravity and friction physics need to be worked on for Crash, it needs to be more natural the movement and velocity that Crash travels. You'd need to fine tune it to be just like in Crash, it is a bit of work but I'm sure you can pull it off, you've got a excellent work with this one. I like this project alone, thanks for sharing.
Thank you for the feedback :) From day to day I try to fix one or two bugs and impove some physics like: landing and wall detection or ceiling. In a few videos here, I have shown what problems and difficulties can arise in connection with Ursina. I'll be honest, a game like this would have to be programmed properly in C or C++, then everything would definitely run faster and cleaner. Sometimes I regret not having learned and used this programming language in the same way I have here.
