I've spent several last years solo-developing an ad-free website with over 50 different solitaire/puzzle games (https://inSolitaire.com). I've rewritten this project (almost) completely four times and tried my very best to make it work on both desktop and mobiles.
I would be incredibly grateful for any feedback – I'm looking to genuinely improve the experience. Specifically, I'm wondering whether it is easy to use and what it lacks.
I have a huge backlog to cover for this, but so far it has been great fun and I have learnt an incredible range of things!
