This was adorable! I want friends under the sea... :(
One thing I really appreciate in this game is the small details that bring the world and characters more into life. An example of this would be examining objects Cilo's home and Am's home shows a bit more detail about what their habits and personalities are like, which helps flesh them out more as characters! There's a couple more examples of this but I won't spoil for those who want to see for themselves. :)
I made a video with my commentary and experiences. Keep up the great work!
