Gravity Coin Flip – a medieval puzzle-platformer where every coin flips gravity. 100 rooms, free in browser (desktop & mobile)

Game Title: Gravity Coin Flip Platform: Web (desktop and mobile, touch controls included) Playable Link: https://galectic.itch.io/gravity-flip-coin Description: You're a little knight exploring a castle, and every gold coin you grab flips gravity, so the floor becomes the ceiling. The puzzle is figuring out where you'll land before you grab it. 100 rooms across 10 themed worlds, each adding a new twist: crumbling stone, slippery ice, sideways gravity coins, wizard portals, a cursed crypt that flips gravity every 5 seconds, and a tower that rotates the whole room. Every room is checked to have a solution, and there's undo, restart and a hint button so you're never stuck. 3 stars per room: clear it, no hints, beat the time. Free to Play Status: 100% free, no account, no ads, no downloads. Involvement: I'm the solo developer, a final-year engineering student, and this is my first released game. I designed the game, mechanics and worlds, and built it with heavy help from AI coding tools (Claude) for code, level generation and music. Every level is machine-verified to be solvable. The knight sprite is a free CC0 asset by pzUH. Would love honest feedback on which rooms felt unfair or which mechanics were unclear!   submitted by   /u/Silent_Start_8079   to   r/IndieGaming [link]   [comments]
