This game is really cute, and I think is the first game with ERB (Unless I missed one), the stylized artstyle is simply astounding, and I'm very fan of it and the atmosphere. My suggestions would be to try to add a web version, at least I saw the Godot Logo, so it'd technically possible (Unless it was made on the Mono Version), but maybe you ran out of time or found some unexpected bug.
I also felt that sometimes is a bit hard to separate the background / foreground elements, so it could potentially be an improvement in Accesibility, Ender Lilies could be of help to use as a reference for the contrast.
Overall, Congratulations to the team for the project , and hopefully that you continue working in this game! I see potential in what you already have.
