Np you can submit real life games and board games. Just that traditionally we tend to test softwares.
What a nice nickname and an avatar you have!:) As a humble human which is a value needed to become even just a spiritual Student (and I'm a Grandmaster) I decided to learn at least game-making SW. So far, I went through all tutorials in GDevelop (which I choose to learn), but I found out, that for an advanced looking game, advanced artworks have to be bought. And I already have huge expenses in the realm of TTRPGs. I bow before you and all other video games developers, especially before the ones who are offering their games for free. Namaha astu te!😇
