Sly Panda is a nice little Pico-8 game where you go after a high score while killing endlessly spawning enemies. It has a unique control scheme where you hold A to slow down time, and then hold B to charge up projectiles, and then release A to fire all the projectiles. You can also press B to dash, which unfortunately results in doing the exact opposite of what you want to do, a lot of the time. If you mess up the timing of the button presses, or don't have enough meter to activate slom-mo, you will dash directly into the enemies you are trying to shoot.
Still, I think it's a game that's worth 5 minutes of your time.
