I paid no interest in Vampire Survivors but as soon as a clone came along with cute anime girls I was in. And hey, what do you know, this type of time-wasting game is extremely fun and addicting. I've completed HoloCure with over half the cast and plan to do the same with the rest. There's a surprising amount of content here for a free fan-game made in the span of a few months, and it's a wonderful love letter to all things Hololive. Highly recommend.
