Looks like you are not only a groovy dad but also a nice dude ;) i feel kind of bad for getting something for free... I mean... Most of your stuff is free/pay what you want anyways xD
The other game i was highly interested in was "Temporal" (i love games with miniatures) and i allready bought that earlier this day... Reads like another good game but have to do some play-testing before i can give a good review... Maybe sunday....
Denying your offer would be impolite so let's make a deal:
Instead of giving me keys (plural) give me one random game (use a dice and reroll if you get M&M or Temporal) and give a hug to a number of people equal to the number of games you could have given to me... double it if you like ;) Hopefully this is not only a win-win situation for both of us but also for anyone around you.
The e-mail Adress on the receipt for M&M (bought via wargamevault) is the same as the one for Temporal (bought via itch) so feel free to pick the receipt that is easier for you to find.
And thank you for responding and being so nice.
