I finally managed to play this game too \o/ And it was really good!
Definitely the most polished entry I've played so far.
The concept and theme interpretation is very unique and creative. The idea of creating your own bullet hell and then surviving it is definitely clever and super fun! My highscore personally is loop 10 which probably isn't too good. :') I'll try it some more, once I'm home.
Furthermore I can say: the character is very smooth to control; the graphics are awesome obviously and the music is mostly very good too. (I love how much it gains in energy, past loop 5 or something!) So everything you'd wish for from a polished game.
Now on the counter side, I feel like the first two loops are a little too slow. At least when you have to replay them often, which is the case, when you are still dying very early into the game. Especially the second one feels a little tedious, since you are just watching yourself. But that's just a little nitpick. My suggestion would be to shorten them a little once you've played through them at least once. I understand, that they are good for the very first run as a tutorial.
Another thing I noticed is, that player-projectiles sometimes aren't reflected correctly, but just do a 180 degrees turn. At first I thought that might just be something they do, but when they reappear in a loop, they sometimes reflect correctly again and go an entirely different route! So I thought, that probably wasn't intentional.
I'm wondering if this is something that only happens on low fps or if others can reproduce the problem too.
Anyway, overall an extremely good entry. You did very well!

Thank you so much for the comment and the nice words, I'm glad you enjoyed!
I can totally see what you mean, and there is definitely something I could do to make the first loops feel less boring, and I'll look at that right after the jam!
As for the other point, this is indeed a bug (and one that is probably going to cause a lot of headaches to fix). I don't know if you were playing on the web version but it does have a few bugs that shouldn't happen on the downloadable one.
I'm very sorry about it and hope it didn't ruin a good run, thanks again!
