Really liking it. Reminds me of Desktop Dungeons and that is a great thing. Here are my two cents:
- Permadeath on party members is annoying. This is mostly because playing with multiple characters (with varying stats and abilities) is more interesting than playing with a single standard adventurer. I would make character unlocks permanent, but using a character should have a cost (money or some other resource). This way the player might need to do some grinding with a single character, but there would be no luck involved in using more characters (after finding a few that is).
- Analysis Paralysis is a thing (on Normal difficulty at least, haven't tried Easy yet). Less enemy types per level would alleviate this, but then again maybe that would be too easy.
- A bonus for clearing a room, for instance full health for the whole party (no monsters around, might as well rest).
-A group of Munchers drops the wolf trap in a random position. It would be quite nice if the wolf trap always spawned on the specific Muncher you attacked, allowing for some tactical thinking.
-When I first saw Evil Root I though it would stick to other Evil Root and together act as a Tetris piece of sorts. The current Evil Root design creates quite interesting situations on its own, so maybe the Tetris behaviour would work in a new enemy type which sticks to other enemies and only falls with them.
