I'm somewhat showing my bias as I do enjoy some of Hololive streams from time to time, but:
It's like Vampire Survivors but free, looks better, has a strafe, each allows more interesting builds since each character has a unique power up, and these characters have a better defined synergy immediately because of this.
I was a lot more pleased with this type of 'Vampire Survivor' clone, so much so that I legit wanted to donate a bit to support the project- but the game's creator has stated they prefer not to receive any monetary compensation.
All things considered while I'm still not as addicted as some to this kind of formula I'll be keeping an eye on updates for this in the future.
