Really nice idea and execution! One nice aspect Is that it is amenable to be played as a coffee break game which I enjoyed :) A few comments: Some items and combinations have pretty strong scalings and it felt like unless you can find the necessary items for such combinations you are doomed to fail in the magma level. I only had three runs, though. In my last run, warrior's spellbook, wizard cap, assassin's dagger, multiple shivs, ring of rage, broken ring, my first wand, two spiked helmets, and a whole lot of mana stones had awesome synergy and was basically unbeatable. I believe all relics boost the damage of items which is not very different than drops that boost damage. In Slay the Spire, I kind of enjoyed that the Boss relics changed the way you played greatly rather than just increasing damage. I'm not sure if it is running the game as a web application, but fighting got slower especially with many conductive items in the inventory. It felt like the connectivities were calculated only when items changed place, but still for some reason spending mana slowed the game greatly. Overall, even at this state looks and feels great! Keep up the good work!
