'Gummy Rain' lets you take control of a flying gun, hunting down the raining gummy bears while some really cool music plays. The game never explains what country you're protecting or why gummy bears are trying to invade it. That's because there's no time for formalities. They're already armed. They're coming. And you must protec.
As for the feedback, I liked the sound effects and responsive visuals like the screen shake, which make the game more satisfying to play.
Pro gamer tip for all the n00bs in comments: you don't need to kill all of the gummies on the screen. Just aim for one and make sure you hit it! This will refill your HP bar and so the slaughter will continue.
Btw my personal record is around 57 seconds.
