1. You can not giveaway free games on steamgifts;)
2. the 2 giveaways which wrote "free games" are not big. one had just 150 keys and it was nothing else as a social media giveaway.
3. we have given away nearly 9000 keys of this game in our groups;) and it's still not a free game.

Feel free to ask the dev. He is in my friendlist.

Free games are games with a massive amount of free keys on indiagala or bundlestars or whoisgaming.
For example 500.000 keys or 2-3 million on humblebundle or indiegala.

And not games which are in small key giveaways from 2 groups which wrote "free game" to create some facebookfakelikes.

But feel free to report the game as free game. No one cares.
You just make the other users angry because they can not win anymore

thanks for the +rep :)
