This game played amazing. Tight controls, easy to gain a "touch" with the shooting. My hint is that the upgrades you want to get in the beginning aren't the ones you want at the end. Early game "+1 dmg" is really good; "+1 hp after losing shield" is really good after upgrading shields; "Ricochet" is amazing first few times you access it. Move at diagonals to beat GREENS, and if they are right next to you you CANNOT fly vertical/horizontal to those boys.
In response to Developer: one way to make it easier to compare would be to have armor replace the slot you just equipped from... that way you can just click and hover your mouse in place. Also, can we get an arrange by cost button? +vote!
Money seems to "cool off", as it falls it becomes worth less. And if your weapon is off the screen it won't fire, keep those near your ship. ^_^b for the tilt option.
