This game is great!!! It's so fun and addicting to play. I have an idea for power ups that I feel would make the game even better. I feel like there should be a mode in the game where you can be able to use power ups that randomly pop out from planktons when they're popped. Some ideas for power ups are instant fever, invincibility for 10 seconds, extra life, a bubble circle that appears around you that slowly becomes damaged when planktons hit it, homing bubbles, explosive bubbles (pops all plankton in the range of the explosion), and speed up. There could also be some bad power ups to, so it's a risk of collecting one. Some examples of these could be plankton frenzy (a huge wave of plankton appears on the screen), limited bubbles (your bubbles are created slower), and plankton armor (plankton take 2 hits to defeat for a short time period).
