Crazy that people genuinely expect a game that cost £2.50 to give out possibly thousands (if not more) keys to people. I have bought the game on Itchio and Steam, it's not much at all and frankly I'm just happy to know you're getting more money instead of losing.
It's more people want the game to still be updated on itch. I twas promised future updates would be given free for people who bought the game. Yet Nacho "remade" the game (When in reality it is basically the same game. I suspect he made it from the ground up but it is still the same game) and won't give original supporters the updated version of the game on itch.io. Where they originally purchased it and where they were told they'd receive future updates for free. I suspect people wouldn't be complaining as much if they were still receiving what they were essentially promised from their purchase of the game. I feel that's a perfectly reasonable expectation.
