what do I mean? got through it! just enter the fertility temple and complete it, that's all you have to do. as soon as you go in go to the back and fight a living statue, then sanu gets upgraded and the pyramid becomes available after that.
I met a new problem. I correctly completed the task of the temple and neko village. But the Hieroglyph puzzle in the pyramid could not be triggered. I got four pieces in time. After I reached the fifth floor and took away the treasure, I could not trigger anything when I returned to the pyramid. This bug caused my entire archive to be completely destroyed
