Platformer Greybox Level Pass

I have a mid-development platformer where the player’s only special move is a tight, responsive double jump, and every stage revolves around gathering collectibles before moving on. My core mechanics are locked; what I need now is a designer who can turn rough sketches into production-ready greybox levels that feel polished long before we send them to the art team.

You’ll get:
• a playable build with the movement, collectibles, and basic camera in place
• written notes on narrative beats and the desired difficulty curve across five planned levels

Your mission is to shape space, pacing, and player flow so each stage naturally teaches, tests, and finally masters the double-jump mechanic while making the hunt for items fun rather than tedious. Please concentrate on:

1. Blockouts that communicate scale, rhythm, and sight-lines.
2. Clear encounter and traversal notes capturing intended beats, shortcuts, and risk-reward paths.
3. Difficulty tuning and checkpoint placement that ramp challenge without spikes, ready for internal play-test.

I’m engine-agnostic—I can supply Unity or Unreal projects and iterate through version control. If you’re interested, share a level design sample or short video walkthrough that shows how you handle greybox readability and player guidance.
