Finally. I released an update through strength and suffering, and finally I released an update! It took me 3 days to find and solve the problems. I rebuilt the engine several times, downloaded different versions of visual studio, and eventually had to completely transfer all the game content to an empty template, so this is actually a completely different game. but of course I haven't fully tested the game yet, so the game may have serious problems with optimization, gameplay, interface, game mechanics, AI, graphics. but I updated the test end, added the camera zoom to the x button, added the 6th map, changed the animation of death.
