JUICE PACK — The Game-Feel Checklist & Tracker for Indie Devs

JUICE PACK — Facet #1: Game Feel

Hi — I'm a fellow indie developer.

I make games because I love it, and I built JUICE PACK because tutorials never gave me this: they taught me to rebuild someone else's demo, not how game feel actually works in a game of my own.

JUICE PACK is my map of game feel: a 40-item checklist across 7 categories, built for indie developers who want to learn the craft and do the work. Every item gives you the principle, why the player feels it, the actual numbers worth starting from (hit-stop 40–80 milliseconds, squash 10–20 percent, pitch variance plus-or-minus 10 percent), and an honest effort rating. Nothing that only fits my game — it works with any game, in any engine, including yours.

It's free. If it helps you and you want to chip in, donations let me keep doing what I love — building tools like this and teaching the craft, one facet at a time. Thank you for your support, or even just your attention.

WHAT'S INSIDE

• JUICE-PACK-Checklist.pdf — the printable map of the facet

• JUICE-PACK-Tracker.xlsx — a pre-loaded tracker with status dropdowns, plus the 10-Minute Sprint log

• checklist.md — the plain-text version for notes apps and repos

• cover.png

• samples/ — three working Godot 4 scripts from the upcoming Lab Editions: hit-stop, camera shake, squash & stretch. Their headers teach the principle, not just the code.

Plus the 10-Minute Juice Sprint: the flat-feature rescue routine. Hit-stop, one particle burst at the contact point, one layered sound. Ten minutes, and flat starts feeling alive.

WHERE THIS GOES

This checklist is the map. The guided path — reference implementations you can feel in a lab, tune, and make your own — arrives as per-engine Lab Editions, Godot first. Learn the facet here; take the patterns there.

And if there's a facet of game development you wish someone would just explain — tell me in the comments. This series grows from what you ask for.
