I unfortunately didn’t have time to make it very balanced, but the idea was you would have to use your ammo/time wisely by factoring the most promising numbers. For instance, you could ignore 64 because it’s a lot of shooting just to get a bunch of 2’s. But if there is a 68, you can get a nice big 17 with only a few shots.
I also did end up making a mechanic where the position on the bubble you shoot influences how the factors will split. For instance shooting a 64 right in the middle will break it into 2 8’s. But if you shoot it on the end, it will break into a 2 and a 32. This mechanic isn’t very obvious though.
