Finally done! And now with a name: Love Craft!
I wanted to do something not related to space, since most of the entries will do that. So I thought in connect worlds metaphorically. “Everybody wants a person to share a life, to found a family, to fall in love, to marry, etc; and when this happen, one person connects its own world to the other”.
I’ve lost so much time on Behavior Trees that I couldn’t add the sounds, what is a shame. However, I kept my initial plan (first time) and I enjoyed the resulting game. It is not that fun, but I liked anyway.
