I'm curious why you're rewriting it for a fourth time? Am I playing version 3 or 4 right now?
Two potential suggestions:
1. You save the game on pause / tab close, it means I'm not able to continue from another device. Would it be possible to provide some form of "seed" that I could input in my other device to continue where I left off? Not sure if that's even possible, just an idea.
2. Option to toggle between mobile/desktop style cards. I understand the desktop style ones might look a bit small on mobile, but I would prefer it.
Great work and site bookmarked.
"Seeding/sharable link" idea is bound to daily game feature – and this is a next feature pack going out in Q1 next year.
Card switch is also in the roadmap, it is part of the non-existent (for now) settings system.
Appreciate for the kind words! Stay tuned!
