I tried this game 2-ish years ago and had a lot of fun with the mage. Very strong mechanics!
This week I've tried a few runs of the newest version and I feel mixed. I miss the electric monsters that zoomed across the field, but I assume they're being saved for other dungeons.
The part I -hate- is the new plant enemies. Almost every run I've had was ended by getting rooted in a spot where I couldn't attack, and I couldn't draw the correct card in time. I'd suggest either A) changing their cross-shaped AOE to an X-shaped AOE so when they aim next to you you don't get hit, B) making them inert every other turn so you don't get rooted several turns in a row, or C) both. I think A and B might not actually be enough when you enter a room with 4 plants.
That being said, I'm having a lot of fun up til that point. Please fix!
