Honestly, it just felt like they were not understanding the choice of going forward with the plan to focus on working on the game for the 1.0 version.
But i do agree that there is a lot of stuff the dev could work on it, but maybe they will during the progress to reaching 1.0
Its not like they going to just slap a 1.0 on it tomorrow and call quits because of their announcement recently
The dev is a nice bloke. We've had a few chats in the past, and he always seemed like he did his best, genuinely caring about the end product.
Could be this project was his way of proving to himself that he could finish a game project, never intending it to be some massive game with a tonne of features.
