First things first, the game looks absolutely gorgeous! I adored everything from all the portraits to the UI and the little wobble the player does while jumping. There might have been a couple too many rooms for my liking, but at least none of them felt like they had a lot of unnecessary empty space, which is often a big problem in these gamejams!
The controls were very solid too, and I loved that your attack is an AoE around you, it was definitely a nice alternative to shooting or swinging swords all the time. The variety of enemies was great, although some of the ranged ones were pretty annoying to deal with and in the end I resorted to the true and tested "just run past everything" strategy most of the time. The compression of every ability into the prayer/attack was a cool idea, but in the end I feel like maybe it was a bit too much functionality under one button, and it made it a bit hard to keep track of all the abilities I had.
Some minor issues I noticed was that the dialogue text sometimes overlapped the frame. The game also took a long time to load and initially stuttered quite a lot in my browser. Fortunately, it evened itself out soon enough, but still I feel like a downloadable build would've been nice! Other than that, some music would definitely have helped tie everything together, but obviously there's only so much you can do in a gamejam!
I managed to get to the top and talk to the goddess, and I like how it seemed like there were several ways to get there. I definitely missed a few stars along the way, though I'm not sure if there was a different ending or any other effect to collecting them, since the game didn't seem to keep track or acknowledge picking them up in any way. Regardless, excellent work!
