Space Pumpkin

Space Pumpkin is one of the Shooting games here that asks for no download and no sign-up. Taps and swipes are the whole vocabulary — a phone plays it best. Listed under alien, arcade, boy, boys, halloween.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Nothing is saved to an account, because there is no account — progress lives in this browser.
