Hi, thank you for playing and for the detailed feedback :)
1. "Smart replay" keeps the same ratio of your last_bet/last_bankroll_amount (So if you had bet 1/4 of your bankroll, it will bet 1/4 of your new bankroll). I will add it to the "How to play" screen
2. Autoplay follows the best "basic strategy" (so the best strategy without counting cards). It actually can hit on soft 18 (A+ 7 value) versus a 9/10/A :) (see here:basic strategy explained)
3. Great idea, I will implement that!
4. I 'll see if I can fit the writing.
5. Nice suggestion, I might do that.
6. I think they still can be useful if you max bet and lose it all. But the more you progress, the less you will need loan yes.
7. For now, there is only 1 upgrade that uses money, I might add more in the future.
8. I will add a way to upgrade max bet more after all the others "max bet" skills are unlocked
9. Mmmmh I see your point, I might change that yes.
10. Thanks, I might work on this game a bit more, even though my code is becoming a little messy lol.
Thanks again and glad you enjoyed!
