Thanks! Yes, at the moment it’s iOS only (iPhone/iPad).
I’m currently working on Android and a Web version as well — the core engine is portable, so those should follow.
A Web version is definitely planned, and Android support is in development as well.
Since the core engine is fully portable, both should come naturally once I’m done polishing the iOS launch.
Really appreciate your interest and willingness to support it on other platforms.
Really glad to hear you enjoy logic puzzle games!
