Thank you for asking Pelayer1! :D
Unfortunately, we haven't really thought about the minimal specs required to play our game ㅠ ㅡㅠ Sorry about not having that ready for you! 
We recommend having a computer that is strong enough to play games like League of Legends! (Sorry for the vague description . . .) Hope you are able to play Sumi and the Soulless Spirits! We'd be so happy if you could. 💚
