Polarity: Evolved

Red and blue enemies need to be hit with bullets that match their colour. Using the wrong bullet colour will empower them making them faster and more deadly. Empowering a level 3 enemy will create an evo that is immune to both red and blue bullets. Collect super bullets to deal with evos which will increase your money multiplier.

Money is your score but can also be spent on bombs and upgrades. Bombs detonate on purchase and clear all enemies and bullets on screen. Buying upgrades or bombs will reset your money multiplier and increase both enemy spawn rate and the cost of your next purchase.

Survive as long as possible, collect as much cash as you can. Do you spend money to get more powerful or save it to build your multiplier?
