So I see a lot of questions about the length of the game. It’s always a tricky question to answer since people’s skill levels vary so much. But I think it’s safe to say that it would be hard to finish it the first time in less than 10 hours. And I think a much more average play time is probably closer to 12. We have 3 selectable difficulty levels from the start of the game (Easy, Normal, and Hard) and one that is unlockable (Crushing!), so you can decide how much of a challenge you want. We’ve also made it possible to change your difficulty setting mid-game, so if you feel you made a mistake a couple of hours in, you can switch without having to start over.
And as for replayablity, we have a bunch of hidden treasure to search for throughout the environments and Medal Points you can earn by showing off your skills as you play the game. These can all be used to unlock some pretty cool secrets (concept art, behind the scenes movies, skins, cheats, etc.)
Hope that answers your questions!
