And now that my gaming year is about over, I'm gonna call it:
Tevi
was my favorite game this year.
I didn't especially dig the anime shenanigans, but I absolutely loved the combo of bullet-hell and metroidvania (bulletvania?). I've never played that particular combination before, and that, along with sharp, fun visuals, a cool (and occasionally awesome) soundtrack, and just an overall vibe of engaging fun make it my GOTY.
