The game art and atmosphere feel really nice, reminding me old time video games. It's nice that you could do the art all by yourself, overall it looks nice aside a few issues, it's quite good.
The game itself is nice to play though it's a bit slow once you understand the mechanics. If you will continue the development you could have an in-game option to speed up the gameplay.
About improvements that can be done:
- When a card is on the table or is part of the displayed trump suit, it's difficult to distinguish spades from clubs, the difference could have been done more marked.
- The Take button doesn't disappear once played a card that beats the opponent. Unless I misunderstood the rule, that shouldn't be possible. I was tricked to take cards that I didn't have to take... :-D
- There is no explanation about the new additional rules, so while I can guess what they could do, choosing between them is something that you have to learn while playing, so it's not much a meaningful choice.
- I would highlight only the cards that can be played, you have anyway already in place the function to check that, so call id directly when the mouse is hovering your hand to help speed up the game and beginner players.
I noticed also that the opponent has his right hand on his left arm. Is that on purpose? :-D
