FAQ
Why not a free model?
Many work, but few show their odds honestly, charge only after the hatch succeeds, or ship tests. Hatchwren does all three.
Why not the $17.99 kits?
They include a trade system and art; Hatchwren doesn't trade yet, and costs less.
What licence do I get?
Licence: unlimited Roblox experiences, commercial use, for you or your clients; no credit needed. No reselling or sharing the code itself.
Pricing
$12 once (.rbxmx, .luau files, Rojo project, example scripts, API docs and the 26 tests). Game Systems Bundle: $25 for all 4 kits (parts $35). Formation, Signal free.
