Hi Eminealth,
Thank you so much for taking the time to leave such detailed and thoughtful feedback. It's excellent!
We agree that RNG is a bit too rabid at the moment and we're working on various ways to improve that. Some of those issues will be solved once we introduce the overworld and exploration part of the game, but free rerolls is something we'll consider.
Another idea we're toying with is upgrade tokens that can increase rarity of heroes.
We're also looking to introduce end of day bonuses that will give your group a specific tag, which will help with getting the combos you want.
Finally we need to introduce more characters that cover specific tags. Faith, Merchant and Thief are currently under represented. We have a whole lineup of heroes that will improve this side of things.
Agreed that day-level ups for specific tags needs to stand out more. Day-level ups in general needs more tuning and more variety.
Altars, is another place where we want to tune things more, we may add more free choices to make them more interesting when you have no gold. We also need to introduce more so you don't get tired of the ones that's there.
Heroes not healing between fights is a design choice, we want to challenge the player with death by a thousand cuts, but I agree that the ways to heal right now is probably too limited. Once idea we've been considering is adding consumable items, like a healing potion or a resurrection potion, that can take the spot of an item, but would provide powerful one time uses that trigger on certain conditions. We'd need these to be impactful enough to offset using an item slot for it, but I think it could be fun.
Thank you again for giving us a lot of great ideas and feedback. Developing in a vacuum is very hard, so really, really appreciate hearing back from you guys playing it. And also very happy you like the game so much! :)
