I can't tell which is a copy of which, but there's an almost identical game featuring bugs rather than slimes. Same animations, same sound effects, same items, etc. Shame too, was looking forward to an original game.
As I said it is the same project, just different editions. Most of my players won’t ever see the other edition because they are not into that niche preference. My original plan was to push this edition first, but I got carried away and released the other one first.
To 99% of my players, this is an original project.
