Thank you for your detailed feedback! I'm truly sorry that your gameplay experience didn’t meet your expectations.
This is actually my very first 3D game, and I’m learning a lot thanks to feedback like yours. Every comment helps me identify bugs and issues I hadn't encountered yet. I’m currently reworking some of the environment hitboxes that can indeed block the player in certain situations. I’m also working on fixing the black screen and crash issues that occur during scene transitions, which you unfortunately experienced.
Thanks again, and I’m planning to release a patch very soon to, as you said, provide the best possible experience for future players! :)
