Streak across a wrapping planetary surface, blast alien landers, and rescue the humanoids they snatch.
You fly a fast ship along a continuously wrapping planet. Alien landers descend to grab the humanoids on the ground and haul them skyward, if one reaches the top, it becomes a deadly mutant. Shoot the landers, catch falling humanoids, and set them back down to keep the surface alive.
Skimmer is a tribute to Defender, released by Williams in 1981 and designed by Eugene Jarvis, notorious for a control panel of five buttons and a two-way stick that defeated most first-time players.
It had a world larger than the screen, tracked on a scanner strip along the top, and the humanoids on the surface are the point of it. Let the abductors carry them all away and the planet explodes, at which point the remaining aliens mutate into something far faster. So the game punishes players who treat it as a shooter: surviving is easy, and rescuing is what actually keeps the level alive.
Skimmer is an original take on the horizontal-scrolling rescue shooter genre, free to play instantly in your browser.
