Omega Quintet is a game that I think that I enjoyed playing, but to be honest I am not quite sure. There was a section that I had to play multiple times because I missed something stupid the first time, and the second time my power went out, which yeah is not the games fault but I was still annoyed. I put off beating it for quite a long time, and as of writing this I still have not beat it, but I swear that within the next day or two that I will beat it.
There were really only two of the girls that I cared for that much which were these two, I know it is a bit of a spoiler to show Aria's demon form but I don't think anyone has played this game in at least 5 years.
To be honest I quit the game not that long after i put that stuff on there. I got to the part where the true ending would be and the battles are just too hard for me and I am not willing to put in the time that would be required to beat them. I have other things that I enjoy a lot more that I should be putting my time towards.
Luckily there were some pretty good CGs that I got right before the place that I decided to quit!
