Alright, here's my thoughts. The visuals and sounds are lovely. The player character is cute, and the chat with capital G God left an impression. I think there's a couple problems with the character abilities though.
The biggest issue I faced was how overpowered the phantom spawning is. With a few seconds of practice I was able to fairly consistently get infinite height by chaining jumps off of phantom heads. The timer in the top left ticks up when I spawn them, so maybe they were supposed to be limited in some way, but that was not my experience (I'm honestly not sure what the timer was for, now that I think about it). It makes it hard to want to try jumping with the (fish?) moving platforms and grappling points when infinite height is always at my fingertips!
The font used for the game over screen was really hard to read, so was the one used for the text boxes but to a lesser extent. I found a point on the map where I fell through the floor infinitely on the far upper right of the god conversation room.
I feel like the phantoms need to be greatly limited if you want other abilities to have a moment to shine. My issues with the platforming didn't detract from my appreciation for the music and sprite work, which made the experience worth it to me.
I wish you luck on your future endeavors!
