Edit: Feel like the game only gets worse when they add so many more items without balancing it, because it becomes harder and harder to get what you want or need, more RNG based.

I put way more time on this than I ever expected to.
Even if it's just a demo, it has a ton of content with the different weapons, armors, relics and consumables.
There's a whole lot of ways to cheese the game, which is good, because it gets demanding on the later levels.
RNG plays a BIG role in it, both on the items you get and the bosses you face. It can be frustrating on that regard, and perhaps will become even more so, as more items are added in the future.
Still, I really enjoyed the great variety of builds available.
