Win Steam keys by playing flash games

I found this site where you can play flash games and by getting achievements you can win coins and with that you can buy the keys. You can also watch videos to win coins. I've already tried it and bought cave story+, so it's not fake.

If someone is instereted i'm leaving my referral link. If you do watch videos, you give a couple of coins too:

Again, i've already bought cave story+ so i'm sure it works.


You can also do some surveys and stuff, but those seem really suspicious. I'd avise to leave them alone.
