I mean at the start DC was developing the game at a good pace, and it was one of the best games on this site in terms of having reliable and reasonably sized updates. Then the updates slowed down, then he started reworking some of his old art (which I don't think was necessary, cuz the old art really had its own charm and didn't deserve to get overwritten) and then the game development ground to a halt. I personally no longer even feel the need to download the game at this point - I know that there's not much, that I'd be interested in, going on.
Dude is making more than ~70k or more a month (most likely more than 100k), DC is legit a millionaire through this game, and from what I've seen his passion has not been there since 2-3 years ago, but this game is like hitting a jackpot and he has likely made more than 5-6 million USD over the years of development, so why stop (I wouldn't)? DC is literally the idol of a lot of those scam devs - he has proven that there's money in this market, and you just have to pull in people early with a good product. Most other games that had a lot of early hype and died down still get multiple thousands of dollars even though the dev only posts wallpapers now, with constantly broken promises on the "next release" - lots of simps and coomers here.
