Hey Fantomed!!
Thanks for the suggestion. I took a look and seems very cool. The only issue is that it needs to be a brownser game :(
Although I might play it during December. Very fun

I'm pretty sure I saw one image puzzle there as well which I unfortunately can't find right now (maybe it wasn't part of confounding calendar and I remember wrong xd). But I found another one, it's listed as a bonus game, but it is there. https://nabokos.itch.io/foxed
Also most games there are made in puzzle script which is rather easy to learn I think.
