As someone who also helped make an astral themed game, this is so charming~
I loved the little character icons during the dialogue — reminds me a lot of Pokémon Mystery Dungeon — and all the side characters are fun to interact with and have unique designs. Cassini's my favorite, his dialogue cracked me up whenever he was on screen LMAO. The music was also fittingly whimsical and it really helped convey the emotions of each scene, I could feel the tension as Gaia got closer to the black hole. Overall, you guys did a great job telling your story!
