That was pretty good, I loved it. Very simple as well tho, so I don't have a lot to comment on sadly.
I guess I gotta get the obvious out of the way and already say that the aesthetics are definitelly the best part of it all, everything looks really beautifull and the characters are adorable x3
I love all animations you made for the Protag like falling by flapping arms and respawning kinda shocked, gave a good bit of personality to her, even if just a little. And I also love the detail on the menu where the priestess does a different animation depending wheter you choose to play or quit.
The gameplay itself is also fine, altought combat felt a little clunky since nothing has a lot of feedback to it. There are sound effects and a few attacks stun locks you for a frame or two, but I missed a little more impact on stuff, like actual knockback or a bit of screenshaking when I get punched by the Bunnitauruses, anything to show that it actually hurted. I liked the bossfight at the end against the priestress tho, It's simple, but I liked that there was a certain degree of puzzle involved by having to bait her into using an attack before getting to close so she wouldn't flee. The battle music is also a banger, but as far as I understood it's not original right? (wich is a bummer tbh, but hey, it's nice to have xD)
Didn't feel very metroidvania tho, since the only upgrade that actually matters is the double jump, and the stat boosters you find doesn't make much difference aside from the atk speed one (wich is found on the main path), but hey. they're still nice fillers to have.
Anyway: gaemplay video if you wanna see it
(Also, if you watch you will notice that I managed to get softlocked twice, first when I managed to fall on a pit before being able to jump, and the second when I interacted with the save stone before finishing the respawn animation)
