Thanks for the feedback! You are playing version 3 right now. Version 4 will be a massive bugfix – I am intending to release it by this Christmas.

"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!
