It seems like only I and few others can play it.
You have to download every file, put it in one directory, setup python 3.6+ and install pygame through pip, then execute main.py from that folder(type "python main.py" in cmd in that folder and press enter), so it's difficult for people not familiar with python.
But there's a solution. You(developer) can make executable file from python script(google how to do it), there's an example in this jam, I'll link it there https://itch.io/jam/mini-jam-105-dreamy/rate/1511798
Contact him and ask how he did it, maybe cooperate on the next jam
About the game, It's ok as a first submission and I like pygame games, but it's harder to do a semi-big game compared to unity.
