I've played it for about 5 hours so far, and I have to say, I find it very charming, addictive, and enjoyable overall. I feel it has a bit of a deceptive simplicity to it - as in, the further you progress, the more the game opens up to you, revealing more and more complexity, customization, variety, and challenge the further you go. The basic gameplay loop is simple at it's core, but I struggle to think of a rogue-like where that isn't the case. I was worried about where I thought I saw the content going in the first two hours or so, but past that I'm continuing to find more and more to become invested in. It's definitely been a "one more turn" kind of experience for me, where I have to force myself to stop playing. I'm going to have some spare time tomorrow, so I'll probably devote a good several hours to it.
I'd recommend anyone trying it to make sure to play for at least a couple hours before you judge it. If that means a "test" whirl, then so be it. But if you end up liking it, give this guy some money. He's very passionate about his game, and has already implemented some features I suggested, like, a day ago.
