I didn't get very far with my rogue - I managed to max one skill (strength) and bump up a few more but couldn't finish it in one sitting, so, with no save abillity, that's as far as I got.
The only feedback I have in addition to what's already been said + what's already in the "Next Step" is that I actually found it a little too easy. My potions bar never went below six (most of the time I had around 11), and toward the end of my playtime I was just waiting for it to get harder - all the enemies I encountered dealt very little damage when they dealt damage at all (they would often be stunned for most of the few turns they got before I killed them).
Making enemies deal a little more damage, so I actually use up my potions, would be nice, especially with the higher-level ones, though I know balancing the too-hard vs too-easy line can be really hard (and based on other feedback I've read, it seems some people have had the opposite problem with enemies I haven't encountered).
Also starting out with less potions/gold or having more things to spend gold on might make them a more meaningful resource.
That being said, overall I found the game very charming. Regardless of whether or not you add more in the future, I enjoyed playing it and I love the art style.
