I love the different take on a somewhat classic game. The AI hand generated visuals are something (going up to eight seems… strange to me). But the audio feedback helps. I think adding a single player mode would help the game, even if it was simple and not too hard to beat.
Also, having an on-screen win screen over a JavaScript alert really helps make a game feel less time rushed (hard to do in a 3 hour game jam tho, so I feel for you).
Cool game overall, great work!
