i really love this game so far! i did run into a bug where i wasn't able to pick up new loot despite having open inventory space. this happened both when i went into the encounter with a full inventory and discarded something to make room, and going into the encounter with open inventory slots already.
if you're looking for any feedback, i think the enemy's card should stick around for a little longer so it's possible to actually read the full effects before it disappears. i also feel like dealing with an arcane barrier is really annoying. it took me well over seven turns once just milling cards to get the arcane ritual so i was allowed to participate in the fight again. the first time i encountered it, i drew the arcane ritual immediately on my next turn and assumed it was just forcing me to spend mana, which seemed like a reasonable mechanic for a card, but just shuffling it somewhere into my deck seems a little cruel.
other than those things, i really really enjoyed this game and i'll definitely be coming back to see how things are shaping up in the future. keep it up!
