Version 1.3.3 Update

This update includes performance and thermal optimizations, accessibility improvements and bug fixes.

Thermal issues and VoiceOver lag

The resource-heavy but ultimately only decorative particle systems based graphics have been replaced with a similar but less expensive effect to avoid the phone getting warm and the battery draining. Also, the game now listens to the system's thermal state notifications. If the device starts getting warm for any reason, Erwin turns off one more expensive visual effect, real-time shadows, and brings it back only once the device has cooled down. Additional decorative effects and animations are switched off when VoiceOver is in use.

VoiceOver and audio

There may be a known VoiceOver issue where speech lags while other audio is playing. To work around it, when you turn off both the background music and sound effects on the pause screen, Erwin's audio engine now shuts down completely instead of just being muted, so that hopefully VoiceOver and the game's own audio engine don't interfere.

The next update, slated for August 2026, will extend VoiceOver gameplay to Multiplayer so you'll be able to play Erwin together with friends, taking turns on a shared cube - VoiceOver users and and sighted players at the same table.
