Just thought of 2 recommendations/additions I'd like to see, what if there was like a beer cake that let you shoot/hiccup bubbles like the ones in the background when you get big enough or some one-tap one-kill type shot. The only downside is that you can't use the normal shots again until your burp, you'd also get pretty big in the process! the second one is simpler, just a boss rush that grows you by one level every win and maybe some type of shrink down area between every few stages
