It's ok if you tell Mofu what to do but others shouldn't?
Holy shit dude.
Mofu is isn't obliged to listen to what people suggest.
If he thinks an idea is good, he's free to add it.
Again...Mofu is the dev here. If he thinks an idea is interesting, he adds it. It's simple. If he later thinks that idea wasn't that good after all, he removes it or changes it. He has total freedom to do so because it's his game.
Trying various things leads to gaining lots of valuable experience for future, more important projects.
If you want to support mofu, then let him do his thing.
