Gravity flip

I wanted to make a game where one button does everything and it still stays interesting. You run automatically, and every tap flips gravity, sending you from the floor to the ceiling and back. That's the whole control scheme. Everything else comes from when you choose to tap.

The levels are built around that. Spikes, pillars and saws are placed so there's always enough room to flip and recover, so when you die it's your timing, not the game cheating. Eight worlds change the look and the mood as you go, from a neon city to the frozen kingdom to the infinite void, and the music speeds up as you do.

The part I'm proudest of is the bosses. Each one fights differently and needs a different approach. One is weak to the big shot you fire every time you flip. One flickers between solid and see-through, and you have to use the right attack at the right moment. One is armored until its core glows. The final boss changes its rules as its health drops. You can run the campaign, try Boss Rush to fight all four back to back, play Endless for a high score, or go Hardcore where one hit ends the run.

There's also a built-in level editor. Build your own course, test it, save it and share it with a code, and a fairness check stops you from making something impossible. Collect coins to unlock skins, each with its own small power, and finish the daily missions and achievements for extra rewards.
