I feel like we shouldn't be awarded with bubbles for advancing the next wave early, but increase score instead. You can simply do five waves or so at a time completely okay (especially with splash damage), and finish most levels very quickly by just advancing waves aggressively. That's my experience playing the game, at least.
Tip: In survival mode, just move your base onto a creeper pool, then before it lands make it move somewhere else. You will never loose as long as you keep repeating this.
I think im a noob, i see all these people saying oh, i made a planet, its easy! but i cant make anything! i kinda felt stupid trying to make stuff colide to make something bigger, but i couldnt, the gravity well didnt seem to do anyhting... i think maybe it lags too much on my conmputer to make a noticable difference.
