I only caught a few minutes of video of this game on youtube a couple days ago. Unfortunately, I have a horrid memory and cannot remember the name of the game, it was your standard Ikaruga-type polarity system. The person playing chose one of the Prismriver Sisters as their character (I think there was a wider variety) which had the other two sisters behind them as a sort of backup?
The most notable thing I could make from the game was that the main score hud was on the left instead of right with the play screen on the right. And on said Hud there was a meter that would gradually fill up by the amount of bullets you display (I think) that looked like a menagerie of autumn things. Leaves, vegetables and such, or something like that.
That's unfortunately all I can remember. I know for a fact that it isn't the one that Jaimers has on his YT channel, so I'm really curious as to what this can be.
