Greetings!
I agree, a bit of color and sound would have made it a lot better. I just didn't have the time to get around to it.
Thanks for playing
The concept is interesting and has potential, though I did loose Venom Kiss twice for reasons I don't understand from 150 HP to 0 and then stalled out the enemy with the other two without ever taking more than 30 dmg. Having voice acting is rare for a game jam and I really like it, but unfortunately it was a bit too repetetive. Overall it is a fun game. Keep it up.
The last continue-it jam I tried doing some hybrid 2d/3d stuff and it didn't work out. So this jam I have decided to start on an even smaller scope. I will do another 2d/3d game, but only the first area. In fact not even that. I am thinking of having a character that can move about and interact with objects that can impact the game, as in change brightness or resolution. In other words it's going to be a glorified options menu!
Additional goal: Since I am doing 3d stuff, I want to create models that I can use to save time for future jams. My own asset pack so to speak. Normally I would create everything during the jam but my past experiences tell me that that is not feasible for me.
Fallback plan: I still have the shambles of my MGGJ10 game that could be recyled. Or maybe just another card game. Hopefully it won't just turn into snake again.
Alright. I finished the story, got all characters, equipment and achievements.
I don't actually know what to write about so have a tier list of my thoughts on the characters and equipment in reverse order:
F tier: Nothing. Anything is better than nothing.
E tier: 1 star equipment. Only useful until you can get the higher tier spirit and artifacts.
D tier:
C tier:
B tier:
A tier:
S tier:
My party for farming 6-3 as I believe it to be the best time/rewards ratio:
Cathy, buffs Seassa
Ayumu, deal ~150 damage to the egg.
Jolanda, I just need an AoE that is not as slow as Harold.
Seassa, instant burst on the big Legion. On average I get 3 crits with super speed and knife barrage but it can get it low enough occasionaly for Yumi.
Yumi, big AoE in Round 1. Often times 60+ damage with arrow to finish off the boss.
2 Rounds needed. Rarely 3 if Seassa doesn't crit.
:D. I didn't realize my gamepad was plugged in and it confused me that non of my controls worked. But after unplugging it worked fine, except for the E key. So I restarted the game and skipped the cutscene and accidently pressed esc again which closed the game.
But as always one of the most visually impressive games in the entire jam with great music and ui to boot.

The game mechanic of turning into a comet is very interesting. I did encounter a couple of problems:
I died and had to restart the entire level, probably needs a checkpoint at the boss. Restarting caused the music to go silent. Only sound effects were left. Then at some point she didn't turn back out of comet form and I was just stuck.
Good job overall though.
It was a fun experience.
However I got stuck after leaving school. It didn't allow me to do anything, neither walking nor opening the menu. But seeing as you have said it should be around 2.5 hours I think it is safe to say that it is a bit too long for a jam in my opinion. A couple of typos here and there but a good entry otherwise.
