Really cool game! I enjoyed the simple art style and lovely vibe in the game. I only played the demo for now but you really got me intrigued to try out the full game. This reminded me of the pokémon snap game on the nintendo 64, which is one of my favorite games from my childhood. This game has a lot of potential, keep up the good work :D
I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)
