@Claude31 (sorry the reply button doesn't work on my browser) In the past, we often produced games in just a few months, but this time we invested a lot of money to create and test a puzzle game with different dynamics from existing ones. The game is clearly of higher quality than the older ones I had published, so we were quite surprised. We also check the App Store and Google Play daily to ensure this gameplay doesn’t already exist. However, one of the developers often uploaded the build to their own account for TestFlight, so we thought that might be the issue, but it's just our guess.

@App Review Hi App Review Team, As advised, I followed up through App Store Connect and also used the contact form you previously linked here on the forum. However, I haven’t received any response so far. I’m attaching a couple of screenshots to show the level of care and quality we put into our games. In particular, one is a new and innovative puzzle game developed specifically for the App Store. It hasn’t been published on any other platform, and we would really appreciate the opportunity to better understand what might have led to its rejection. Thank you for your attention — we’re looking forward to your feedback.
