"Game Where You Press Space to Jump" — Too Many to List, Need Details

Hundreds of games use Spacebar = Jump. To identify yours, I need more:

• Genre? Platformer, endless runner, puzzle, rhythm, FPS?
• Visual style? Pixel art, 3D, vector, minimalist?
• Notable mechanics? Double jump, wall jump, momentum, grappling?
• Setting/characters?
• Singleplayer or multiplayer?

Examples: Super Meat Boy, Geometry Dash, Celeste, VVVVVV, Minecraft, Roblox, countless Flash/HTML5 games.

Give me a detail or two and I'll pinpoint it!
