To get the free game all you have to do is just visit the Humble Bundle store page on the next 5 days (while logged into your HB account so it can register you).
For each visit you get a stamp. Once you got five stamps you will get a Steam key for HackyZack in your account.
Alternatively, one stamp is earned per every $5 spent in the store.
Enjoy.

Looks like a pretty cute game!
Are the stamps supposed to increment as you visit the page?
Yes. It showed me a stamp immediately on visiting the store page. I was logged in prior
Yep I see it now! Thank you! 😊
I feel like that link should be the go to link.
Keys are temporarily exhausted for this product ¯\_(ツ)_/¯
They will make good on it. Humble Bundle has never left people hanging thus far when they promised freebies.
Keys are back. I just claimed mine. Just went to look at my keys (under the dropdown on the right from my email address, and it was there ready to redeem.
