Lumiflip is a pixel-art speedrun platformer built around flipping gravity. The player runs, jumps and turns gravity upside down to walk on ceilings over spikes, swings on a lasso and collects glowing lights on the way to the exit. It has a campaign of hand-made worlds with medal times, multi-storey quests, an endless survival mode chased by a wave, endless dungeons with stalls and boss fights, a daily challenge and a weekly tournament, ghost races against each map's fastest player, online rooms, a couch mode for up to 8 players on one TV with phones as controllers, co-op puzzle maps, a level editor with shared player maps, and a bazaar with outfits, pets and fireflies.
