Thank you! Yes, as you guessed AI has an intelligence level on each stage. In first it's 6/10, in second it's 8/10, and in third it's 10/10. AI decides if cards are useful or not with his intelligence score. But even 10/10 intelligence is not perfect because you won't have any chance to win. So we can assume max intelligence is something like 11. But in 10 intellect, it tries to do its best. It was really pain to write that system in 48 hours as solo. It has more than 2000 lines of code for every different situation(Most of them are switch statements xD). In 10/10 intelligence he will probably counter most of your attacks, but sadly I think 6/10 was too low for first stage because its actions feels like random.
I agree with, I don't see this as a single player experience too. So I'm going to make this as a tabletop card game. I will add different cards and more features while respecting the core elements and gameplay. If you have any ideas for it, please let me know. If you liked that, you will like final physical version too. I will create a Kickstarter project in the future when I add things that will break repetitive gameplay of this game.
Thank you for your review, and I'm glad you liked it. Have a good day ^^
