Well, if it's the same engine, same mistakes... What's the point of that new game? Just another story?Apparently you are, given how you say that all it needs is to be remade in a new engine... Which his second project isn't.
It's still Unity, we just currently don't know if he's still utilising Fungus.
And it's hard to fathom how these two games could be the same. As an example, the new game got tons of customization options from the start, and in The Twist we just have a few. And they are bugged. Like tans, tattoos etc...
If it's the same tech in both games, then The second game got the benefit of better planning. Advanced features are here from the start, while the first one got them partially at the end and with technical problems.
Anyway, If it's the case, if it's just more of the same, then it's really disappointing.
