For all the marbles - there's will be more novels as soon as this one and other 2 are done
NEKO-NIN exHeart +PLUS Nachi
NEKO-NIN exHeart +PLUS Saiha
Highway Blossoms
and many others

Usually i will giveaway stuff that i have already in my steam library... some will be AAA games that i own and just got extra copy from humble bundle

NOTE: all keys are from humble bundle that i haven't redeemed for the same reason - i already own them :)

Good luck <3
