This is a very solid game, notable for not feeling janky or unfinished or light on content at all. Good curve of power scaling that is noticeable and makes you feel good as you power up and get new gear, at the start you're very scrappy and making hard decisions about new equipment vs. sorely needed healing, but at the end you're a powerhouse, and that always feels great. Some really nice new gear to be surprised with later, when I had thought I'd seen everything. Also love the autosave at the start of a floor, forgiving but still a little punishing for failure. It took dying a few times to realize some of the chests were random, they really felt intentionally designed with what you get from them. Audio was great too, the inn music wasn't anything special BUT it always felt good to hear it again, it was like going home to a safe place.
Since there were almost no bugs I do feel the need to mention the few things I noticed, although I assume you must already know about them since the game feels very tested.
- On the Annihilator floor, the door colors stopped working/being correct, and there may have been a few other floors after that with some door color issues.
- There was a bug in the player's favor that sometimes when you buy things, particularly large healing potions, you get two of them instead of one, that happened to me several times.
- Once when I stacked two of the best potions on top of each other, I swear the stack "ate" the second one, and I died on purpose so that wouldn't happen again because they're so valuable, didn't stack them the second time.
- One time when I died, I suddenly had 3 of the best potion in my inventory. I assumed this was some kind of player aid mechanic for dying. But then when I died and restarted again, I only had one.
- One time I discarded a gem to pick up another item, and I assumed that discard would drop it on the floor like other floating items, but it did not, I suppose that's on me for assuming. Then with the space freed up from the gem, the other floor item did not want to pick up. Maybe I wasn't standing in just the right spot for it. I moved some items around in inventory and then it did eventually pick up.
- Throughout the game I picked up 2 or 3 extra rusty keys, and I was excited at the prospect of getting to the end to open a bunch of extra doors for my foresight in keeping them, but this did not happen. :) I always enjoy stuff like that in games, something that can happen in a few Zelda games.
But overall this was a really nice game and you should sell it immediately on Steam for $1 to $20, whatever you think is fair.
