There is no snap for Komorebi either, and Komorebi seems not so straight forward and user friendly. Hidamari is for Wayland, too.
Currently there is no easy way to get a live animated wallpaper on Ubuntu.
Hidamari is written in Python. There is a flatpak, but installing flatpak support on Ubuntu is dreadful and requires terminal, which no new user will do. Most use what is in the Ubuntu Software. I think we need these little details and treats such as live wallpaper on Ubuntu found and installed simply.
The Hidamari developer has been contacted and he is for a snap package, but will not do it himself: https://github.com/jeffshee/hidamari/issues/71
