Everything about it is like play testing some dude's "great idea for a board game". Nothing about it feels complete or fully realized. But it's got this DIY/underdog clout, which disaster criticism.
It is _not_ a good game. Not right now.
Sure, it's a roguelike. But GOOD roguelikes are rarely unfair, and with skill you learn to avoid certain situations and what risks are worth taking. You can almost always see where your mistakes were. In Dream Quest, IF the boss isn't behind a wall so that you can't get to it, you're more likely to die just because you've cleared the level and there just wasn't enough stuff for you to have a chance. Most of the time there's no way to afford most of what is at the shops because there's not enough money in the level.
This is not because of scrappy, garage design. It's because of unfinished development.
