Hi everyone! I'm the developer of HAP, a co-op puzzle platformer, and I'm looking for first-time player feedback on the opening puzzles.
HAP received the 2nd Prize (Track 1) at OpenAI Game Builders Seoul 2026.
Official winners announcement: https://openaigame2026.com/ko/news/winners-and-highlights
Two players share a world split in half. Yang walks on the floor, while Yin walks on the ceiling with reversed gravity. Where their opposite lights meet, the world turns green and creates a way forward.

If you can try the first 5–10 minutes, I'd especially like to know:
1. When did you understand what you were supposed to do and how the two characters work together?
2. Where did you first get stuck or confused? What did you try at that point?
3. Would you want to keep playing? What made you want to continue or stop?
Please mention your platform and any download, setup, or control problems too. Feedback on the English instructions is also welcome.
I use AI tools during development. I'm looking for feedback on the actual play experience, puzzle clarity, and controls.
Thanks for trying it!
