Following the example of Thomas Biskup, the Creator of ADOM, I have opened a shop with some items related to HyperRogue. I hope you like them.
If you want to see items based on specific areas in HyperRogue, or on one of my other games, comment here.
I don't really expect to sell anything, but why not try?
Of course donating would be a more cost effective way of supporting my work, but you don't get a nice T-shirt (or other item) for this :)
