[…] about some Celeste game-feel tricks. I don’t think that we invented any of these techniques, but they are important parts of the moment-to-moment experience of Celeste.

1. Coyote Time
2. Jump Buffering
3. Halved-Gravity Jump Peak
4. Jump Corner Correction
5. Dash Corner Correction
6. Semi-Solid Popping
7. Lift Momentum Storage
8. Wide Wall-Jump Window
9. Even Wider Super Wall-Jump Window
10. Stamina Refunds

You might have noticed a pattern! All are centered around widening timing or positioning windows, so that everything is fudged a tiny bit in the player’s favor. I think that this is a big reason why Celeste can feel kind even though it’s very difficult — it wants you to succeed.
