Don't know why.
The key is from one of my first bought bundles on indiegala.
I didn't see the steam key until clicked on "redeem key" two weeks ago. So I assumw(d) the key was never been activated before. It could be my fault or the platform (display).

I am sorry for that.

Anyway, if you agree I will send you th key via steam ingame gift. The game is on sale the next three days for €0,49. That is whst I can and will offer to you.
I think we need to get friends, because my steam basket says it can't send the key to your steam acoount
