This is definitely one of the more unique games I've seen in the jam, and one that kind of came out of nowhere and impressed me.
The intro is done without text or dialogue, only slow animation and shifts in music. That was a risk, but I think it paid off. The style is unique and the game stands out immediately because of it, and the storytelling works surprisingly well. Even if it hadn't worked, I'd give it props for trying something so unique.
The visual style is carried throughout the game. The biblically accurate angels are not really to my taste, but they're well done with great little animations and all the sprites are consistent. Luci's animations are charming, too, and the subtle parallax scrolling in the background really adds to the fluidity of the experience.
If I were to nitpick, I did find the closeup of blob hands in the intro a bit silly and a few sprites had jaggy edges or stray pixels visible when fullscreen. But those are really small nitpicks, and on the whole the graphics are fantastic.
I think some of the mechanics could be better explained. I forgot what dash was for half the game and then it took me a few tries to figure out how to use it, I didn't understand the difference in the two types of health until the last round, and I'm still not sure why only some enemies damage me despite seeming to fire the same projectiles. I also found some of the iconography confusing. None of this is deal-breaking, but could be better explained.
I found it pretty hard to dodge projectiles, between Luci's huge (and unclear) hitbox and slow movement speed. I think this was deliberate, though, to force the use of dash, but I was always reluctant to use it because I didn't have a lot of charges and didn't fully understand how to use it.
I did manage to finish the game despite absolutely sucking at this kind of game, though. It might not be challenging enough for some players but I found it about right for me. Not super hard but not impossible either.
I think the only thing I truly found disappointing was the ending. I was expecting something great like the opening sequence, or at least something more than a game over screen with my final score. It sounds like that isn't the intended end of the game, though, so I'm looking forward to seeing the real ending someday.
The other minor nit I'd pick is that the web version has a quit button which causes the game to just kind of stop. It should probably be removed or behaviour changed.
All in all a very unique and charming entry.
