>>11801894It is a new game (the facts get messy because barely anyone has played both), but it shares basically identical physics, the same general flow and a lot of the same level design ideas, the enemies make the same face when you hit them, the games shared a lot of staff, etc. It's not really confirmed anywhere, I don't think, but its very easy to surmise what happened. If anything, this explanation is much more likely than the only feasible alternative, that a team of half the same devs accidentally made a nearly identical game
