Hello, and sorry for the late reply!
What seems to be the issue for the 1st game not working btw?

nah, I'm sorry. My reply is way later than yours. Haven't checked itch in a while. I tried opening the first game in joiplay. I downloaded the pc file. Unlike the second game, it didn't allow me to play it. It just said this file isn't compatible or something. I'm sorry my memory is terrible. Thanks for the help!!!
