Offering the games for free is probably only a good idea if you want to get people like me to watch them. You have now done that ;-)
I only pay for games with Paysafecard, which is not possible here at itch.
I only buy games from GOG.
I found several games of yours that work on my system and that I like.
I never really spend a lot of money on games. If only because I never know for sure whether games really work for me. I use MX-15 Debian Jessie 32 bit and Wine 1.6.2-20 for Windows games. Your games work perfectly on my computer.
If you had offered a bundle on GOG with the games Circulate, Cubology, Darkside, Kitten Sanctuary, Mirror Mixup, Pyracubes, Scavenger, I would have bought it at the sale for 10 euros at the latest. And the games together are at least worth that.
