Why Eets Munchies is not giftable ?

It doesn't have a store page, I believe it's still in beta.

Because you can't buy it on Steam. Munchies is the second game, and not in the store.

That is not Eets Munchies

Thanks for give a reply.
I thought they are the same.

I can't find the store page for Eets Munchies. Please link it for me.

Eets Munchies doesn't have a store page because it's not available for purchase yet. A beta was given out in one of the humble bundles, though. When the game is released, those who got it through the bundle will get the full version automatically.
