Okay so, this one is a weird one.

Basically, back in the 2000s, I used to travel a lot with my family. We mostly used Qantas, which I'm 99% sure featured this game as I remember playing it on the Airbus A380 on the way to London in 2012, but also flew on Virgin and Malaysia Airlines.

It was this bullet hell vertical scroller kind of like chicken invaders and other similar games in that genre, but themed after mythological creatures and demons.

In it, you play as Hel, goddess of the underworld, trying to escape into the world above, but demons and such from various mythologies try to stop you. I think you shot these sparkly bluish projectiles and that was about all, I don't remember much else.

In area 1, the first miniboss I think was like a small moose skull that floated around and did stuff but I don't remember much.

After that the big boss I remember most distinctly was this giant humanoid moose creature covered in fur with a moose head but humanoid body shapes (basically a furry). This guy would ram into the sides of the screen/side walls and cause waves of giant icicles to fall down on you.

The next bosses I don't remember much about mechanically, but I remember a bit more about them thematically.

I don't remember jack about Beelzebub, maybe his background was greenish?

Azazel, however, was the boss of a very mechanical, industrial, kind of steampunky underworld sector. The background was all metal and cogs and stuff. IIRC he was basically a big gun with a demon head attached, or something like that.

Finally we had Lucifer/Satan. I know Lucifer was part of a dual boss fight but I don't remember who the second boss was. They may have separated Satan as a different character. Lucifer, however, was presented in his angel form, and the background I think was more reddish and may have been a sunset or something.

This is pretty much all I remember, and I just want to know that I'm not crazy and this game existed. I just want to see if I can find any remnant media about this game and learn more about it, so if anyone even has any idea how I can find more about this please let me know.
