I know it's not the creator of this game based on the update done a week ago and that game's preview being nothing alike in terms of UI. But outside from that? Functionally the same game. Instead of 1 000 000... it's 999 999 999. Which... eh.

Just found a third game in this format today: https://stripedbutterfly.itch.io/surviving-magic-academy-as-a-demon-lord
Which seems to be taking more cues from the other game than this one, ironically.
