Really enjoying the game, but it feels a bit unbalanced to me. It's possible I'm still not good enough at the game to form these opinions, but I've played quite a few runs, so I'll try to elaborate on what I felt while playing:
Not being able to see enemy intentions makes it hard to understand how much damage they can deal and plan accordingly. I think their damage is a bit on the higher side, too. Low roll dice are pretty damn low and you're stuck spending energy in order to get rid of them. Those make it feel unfairly difficult to face certain enemies because you low roll and must face tank 10+ damage early on. The bee queen one-shot me even though counting shields I still had about 27 hp, so it feels very unjustified to just die because of a low roll when enemies deal so much damage. That also makes enemies that have sustain like heals/shields take too long to fight and makes the fight rather unsatisfying, especially in certain enemy setups. I'd recommend either improving low rolls or reducing the insane damage enemies deal across the board. A way to discard dice would be nice, but maybe glass dice could break if discarded.
Minor criticism would be that the random events could be improved imo. The one where you lose a random die or half hp feels like too much, while another, like the one that skips floors, I probably avoided about half the time. They feel either too punishing or just uninteresting, and I think it's more a conceptual issue than a numbers issue. Post-battle options can be a little unsatisfying more often than not, so maybe 3 choices could be good, if alongside a larger pool of options to possibly get. I'm less confident on this paragraph's suggestions as a whole though lol, just think these aspects could be improved is all.
In terms of general feel I think it already feels pretty good, but I'd suggest 2 QoL improvements: Confirmation if finishing the turn with energy left (and a less discrete Finish button), and a way to swap a die with another by dropping it on top.
All that said I've been enjoying the game a lot. Thank you!
