Ho I thought you meant he should make his own engine not switch to an already existing one ! Yeah indeed it would be much faster, but it still quite a load of work tho.

It's not that I refuse to see some bad decisions have been made, well rather some good decisions haven't (yet?), but I think your opinion is too extreme as there probably are some things we don't know about or didn't consider which results in having the game as it is now, in the present time, and not what it looks like in our wildest dreams.

Making a good early-access indie game is a long process made of choices and compromises, it takes time and patience is the key



Edit : fixed typing errors and non-sense, I was barelly awoken xD
