I was seriously raging at how bad I was at this game. For the life of me, I could not reach max tank size. Then I finally remembered, what it said about bubbles being harder the farther you get from the started bubble. DERP. So i started spiraling around the starting bubble and finally finished the game! My gosh, it took me forever just to figure that.
I love the concept and system of the game itself, also I'm actually fine with the daily energy system, it just means i'll take a break and check in later. Also waiting on card research ucks but same concept, i like how you don't need to be on and it stills counts time. Basically like an AFK system. However I truly detest the P2W system. That part just ruins it for me. Not so much that I won't play it, I actually find it pretty fun however it makes it hard to progress and just takes away the game's integrity.
