I'll start by saying that IMHO this stretches the theme a bit too much since usually magical girls start as regular girls or at least try to pretend to be normal girls (princess from magic kingdom living undercover!), so the character starting as an angel that turns into a demon and then charges straight up to challenge the heavens really feels out of scope to me.
Now that aside, it's still pretty charming and cute which are magic girl staples, great intro cutscene for a jam and great textless/speechless exposition. Gameplay is simple but fun, catchy music, plus I'm a big fan of weird biblical acurate angels. Ending however just felt like a downer, in particular considering all the effort put into the intro cutscene, but we really get no explanation of why protagonist was cast from heaven, also we don't see the other sister angels after the intro. Ends up feeling more like a demo/intro for a bigger game, but even those usually have one boss (in this case one of the sister angels would've been perfect me thinks). Like you already went through the trouble of designing great art for the sister angels for the intro, I don't think it would've been that hard just using that art for one of the enemies then extra health/damage, make them show up at the end, there.
Also +1 to "hold ctrl button" to shoot.
Nitpicks aside, again great art and fun gameplay!
