It is, but the port does have issues. I had all my ascension progress wiped one day, despite keeping achievements and records of earlier runs. Support eventually got back to me and said it was a known issue with no expected fix date, and offered me a refund. Besides that, there were regular issues where the game would crash often if you rotated your phone orientation and the opening menu sounds would play even if you had everything muted in settings.

I got it for PC and it’s a better experience. Besides fixing these issues, you can also add mods.
