Ghostly Spikes

Ghostly Spikes is one of the Adventure games here that asks for no download and no sign-up. Taps and swipes are the whole vocabulary — a phone plays it best. Catalogued as 1 player, clicker, fly, ghost, halloween.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Close the tab and come back later; the game is still one click away.
