In my experience, devs are very open to suggestions to help those with CVD - especially small indy teams. The main developer of Button Up!, a similar-but-not-really puzzle game was kind enough to listen to my input early on and add hints in the form of size differences and dots in the circle (which indirectly lead to the current theme of stitching buttons, actually!)
Project Title: Button Up!
Promotion Type Feedback Wanted
Developer: Me A new type of puzzle game, it's a bit hard to describe which is why I'm after feedback! But, I've had overwhelmingly positive feedback on the puzzle element. Most mobile "puzzle" games rely on luck, but I've designed Button Up! to be challenging but fair, if you're clever you score highly, if you're a bit thick, well, not so.
Google Play: Button Up!
iOS: Under review, maybe next week!
