Hi VampiricKnight! You're correct in that this is pretty much an all new and self-contained story. It has nods to the original, but I wouldn't say that you'd miss out. I'd recommend having played the original or at least it's demo, just for kicks. =)
Thank you for the question! And yes the Android build has been surprisingly popular! Actually, in downloads, it's beating the Mac version. Which I never would've expected tbh
