Hi, nice graphics and nice world generation. I also really liked the void effect when the curse happen.
I find the character too fast too quickly, making him a bit of a soap and made me run into traps so much time when I definitly tried to avoid them.
Also, while the world generation is cool, it take soo much time (since I died often, I felt it a lot), maybe you should try to accelerate it using some parallelization. Or, since you're using godot, if your world generation algorithm is made on GDScript, maybe try to make this algorithm in C++ using GDExtension, this would boost the generation by a lot
