Played this a bit this afternoon. It seems like a really solid start, and I think, if it was refined a bit, you could maybe commission art for what each encounter is and sell it as a hand the size of a deck. It would be like if One Deck Dungeon had an OSR version, lol.
A few thoughts.
- There's no endgame goal after hitting Lvl3
- A Boss battle could fulfill this lack. even making a rule to generate a Boss each dungeon might be good.
- Setting aside the Kings might be simplest for bosses, with each suit being a different boss.
- If you wanted to get real fancy, Kings could be trophies after defeat. Maybe discard for ADV?
- There's no generative rules for the dungeon for people who aren't creative (or who weren't feeling creative this afternoon). How would a robot carry out the game?
- With a strict minimum dungeon size peeking, abilities seemed lackluster. This was accentuated if they were in a straight line.
- Is there minimum cards in a dungeon the minimum needed to be completed? Could you complete fewer than the minimum cards if you swapped cards using Mage lvl 3 ability?
- Is the lever puzzle starting with the first card face up? What is the player guessing against for the first card if they're all face down?
- Was 15+ arbitrary?
- Was 35+ gold arbitrary?
- Wealth felt too abundant. Leveling was easy.
- Maybe 3 loot slots, with loot cards face up. So you're trying to maximize the value of 3 cards.
- Does a player ever permadeath? Different lose states that mean just losing your loot, or starting from scratch might be fun.
- Does health always replenish between runs? What would be the benefit of continuing with just remaining health?
- What would an "endless mode" look like?
- Maybe have the cave in force a detour adding cards somehow?
Sorry this was so long. You're probably done thinking about this game, anyways.
