So in other words, the dev said to himself:
"I'm running out of ideas, whatever shall I do? Oh I know! Let's make some minor changes to this game that I made that got popular due to what was essentially blind luck, and call it a sequel because I'm greedy and people are stupid enough to buy the same game twice."
This can only end well for everyone involved. /s
Yeah I'm being a massive downer and will probably get a lot flack for saying that, but I really don't give a flying fuck.
