Better!
Like movie sequels, I think this is in fact the best in the entire series. This really works for me because you try to make it quite simple with how the tank gets bigger. It can get annoying when you have to get upgrades and when you do, the tank just becomes bulkier. This also seems to have really slick graphics as I love how smoothly the bubble tank can fire. While a simple game, there is still a lot of detail put into it. It's like your future stuff did not do as well because it tried to be more elaborate.
Everything about this is just cute. Apart from the premise of popping bubbles, you also get to hear that neat little "bing" sound whenever you pop something. This is the kind of game where you can really relax and just take your time. It's a bit repetitive, but still lots of fun. It just goes to show that the best things in life are simple.
