I hope this is clever marketing from the developer because I had never heard of this game until now and also because I can’t for the life of me figure out why anyone would abuse an indie developer for $2.
I understand some people might do that, but they’d have to be a tiny percentage.
Yes, some people will literally waste 100x more resources, in mental energy and time, than the price of admission to complain.
But my point was that this type of criticism can be ignored - if you get 1000 sales and 2 people turn out to be dickheads you shove them in the (mental) bin.
