The core of the issue lies in the fragmentation of the game on iOS.

Once the Binding of Isaac: Repentance IPA is successfully installed, the depth of the game becomes apparent. The mobile interface has been refined to handle the "vibe" of the basement, with touch controls that are surprisingly responsive, though physical controllers remain the gold standard for high-level play.
