Soo I think just about all my comments will be stuff you are already aware of, and from your Discord comments it seems like there's some really impressive stuff going on under the hood, but the game itself is a bit underwhelming. It would have been super cool to see some of the roguelike powerup elements you mentioned, if the jam deadline had been a bit more cooperative. The functionality of the bubble shooter itself feels nice, and coupled with little bits of polish like the dotted line animation of the aimer and the touch of highlight on the bubbles makes for a satisfying experience. I really dig the minimalist aesthetic you have going on, the color choice is great too. Obviously, sound/music, a win/lose condition, etc would help make the game more fun and complete, but you are already aware of all that. One minor critique is that it got annoying to re-select the color bubble after every shot; I would have preferred the next bubble being auto-selected, and then if the player desired being able to select one of the other colors. I think you've got a good foundation for a balatro inspired bubble shooter, and wish you the best of luck if you continue with it, nice work!!
