Huh, pretty interesting game! Reminds me a lot of games like Balatro, Luck Be A Landlord, Peggle and so on, as it's got a certain gambling appeal to it. Overall the game seems very promising: the presentation is polished and charming, the core loop is simple but addicting, there's some good informative feedback through effects like number pop-ups as well as the log, there's some cute affectations like being able to interact with the portraits, and there's a lot of strategic potential in aiming and equipping your dice. Very nice!
It's very promising for an alpha, so in the interest of helping, here's my feedback:
*I wish there was a tutorial because there was a lot of aspects that took me a long time to learn. For example, I had no idea what the aiming cone was or why aiming away from it gave a bonus, until I learned that the golden dead center seems to always be an optimal calculated shot. It's also so difficult to keep track of all the numbers popping up and the reasons behind them, like how once you hit all the dice it triggers all of them again (I think?). In general things happen so fast and it can make things unclear: I didn't even realize the dice were rolling since they stay still and instantly change without some sort of animation for it.
*It's a bummer that you can only read the last lines of the log. I wish I could scroll through the log to be able to review everything that's happened as it would really help me understand.
*Maybe it's part of the appeal or maybe I'm just not good enough to see the game at a deeper level yet, but it does feel like the game is so wacky and chaotic that it's practically all up to luck. I like it when there is some sort of strategy or improvisation skill I can get better at, and while this flirts at it with all the sticker effects and aiming, it feels ultimately uncontrollable, so should I really put in any effort beyond just randomly applying stickers and always aiming dead center and hoping for the best? At that rate, it just turns into a slot machine where I keep cranking it blindly, and that isn't my jam (but I can see the appeal, so it's up to you).
*In order to better grasp everything that's happening and feel rewarded when you get something special to happen, I'd suggest that the game pause or go into slow-mo at critical moments such as when you hit all the dice or trigger a synergistic sticker effect to highlight them. Obviously this comes at the risk of becoming tedious in later rounds when so much is happening and you're used to it already, so I'd suggest adding a 'fast-foward' function, and that the current gameplay should be this 'fast-forward' mode.
*The game is already pretty juicy and satisfying, but it nevertheless still has a rather dry feel to it due to the plain black background, lack of music, and lack of distinguishing/rewarding the act of pulling off rare events. Gambling is all about the jangling keys, so jangle them even harder with increasingly pitch-shifted sounds and all that jazz!
