To answer the questions:
My favorite part on making my game was implementing some of the features I have never done before, which there was a lot and I managed to fit a fair amount of my ideas into the game, and that feeling of succeeding on adding something entirely new for the first time gave me a big sense of happiness. Still had some cool ideas left out due to losing almost a whole week of development to irl stuff. Buuut I might see if I can add some secret paths with all the other cool gimmicks I had in mind as well as adding polish to the things I think fell weakest at. As for making new friends, I didn't explore that much into that part because I worked on everything as a solo dev. But this being my first jam made me realize that there are a lot of talented people here and there will be a lot more to meet in future jams that I may soon take part in.
