It's still pretty much a WIP and a pre-alpha build. The Dev seems to be releasing builds to showcase new features and nothing else. Yes it only has one level so far. The previous level you can find in an earlier build. Ask some users for a copy of it.this game only 1 level to finish? because after defeating the boss zombie i can't go no where
Its prequel is totally complete and very playable. You can find it here
Check it out if you haven't already. Btw since you're here and seen the tags, I assume you're okay with ryona and guro.
But you probably already knew all this already.
