it's clear that there may be other ways. for example, you can manually draw the shadows, but it's quite a hassle, and I don't think you'll be doing that. Perhaps you should find someone to help you with your work, as there are many skilled artists and C# programmers on this website. I've looked at your code, and it's well-written. You've done a great job. However, there's something you need to do with the sprites, and it's crucial.

bro are you seriously drawing every human sprite separately? how about just dividing the sprites into several parts and stacking them on top of each other? this will help in the future and reduce the weight of the game. but you really need to work on it, do you have enough time?
