Wait until you find out it's incredibly easy to copy and edit Live2D animations, trace art, and rip Ren'py code and assets.Btw, it's not just the art which is identical to IW, but also a lot of the scripting on top of the ren'py engine. Their custom menus are identical and most damning of all their use of Live2D. If it's a rip-off, they're somehow ripping off both the art and the programming from Sad Crab. That's not what's happening.
I don't think that happened here, but saying they'd have to "somehow" manage that, as if it were difficult, is silly.
