The face of the list. Played it for the first time years and years ago, and never quite found another that scratched the same itch.
Humanity
Manifold Garden
This game asks: "What if repetition?". The most visually impressive thing is the credits, which is quite the choice
Creeper World 4
Against the Wall
What if wall. It's the barest alphaest demo you've ever seen, and it seems to have been abandoned ages ago, but it's a neat concept
Creeper World 3: Arc Eternal
What if RTS, but fighting a liquid?
Holocure: Save the Fans!
This one is here because it's weird that someone made a vampire survivors clone that is better (imo) than the original, while also being about v-tubers, of which I know nothing so playing this is a fever dream of references that go over my head
