Thanks for the detailed feedback!
Controller clarity is definitely a problem as it doesn't give you any feedback to what the square button is at first. Can definitely add something like a "check your controls by clicking the icon in the bottom right!" after the jam but for now I'll add something on the itch page.
My idea for generating strategy was that as your hands have different strengths, they become more or less powerful (I.e having the advantage in a tie), coupled with the fact that each game is worth different amount of points (where winning games worth more points is better) then suddenly it's not fully random but you can see where the opponent could prioritise their best hands. Like the layers of bluffing in poker.
Obviously the execution or the weighting of the above wasn't as strong as I would have liked in this case (or I didn't explain it enough in game), but that's just the nature of trying things in game jams!
The UI definitely needs improvement. The arrow thing was a holdover from when I was going to put a 2 player mode in where you could need to keep your actions hidden from each other.
Do you think this game would work better in person with another human player where you could adapt to their playstyle and have those interactions with them?
