Finally got the impossible badge - things I found useful:
- pawn that are promoted to a queen and stay as a queen until that level finishes
- get cantrips early, especially if they are on pawns
- save coins after the first level for a greater chance of being able to get a cantrip in the second shop
- if you get a goblin archer on level 3 kill that last as you can get closer to it without taking damage
- buy as many shields as you can
- reset button is your friend but wait until after 2nd or 3rd level to us it as RNG can be kind with coins/shop prices
- it's not about speed but planning and luck, keep an eye on your deck to see what is to come
- kill as many blight matron as you can early on in gauntlet as when they move they leave underneath them reducing the number of safe spaces you'll have later on
- kill blight matrons on the edge of the board or with other enemies/self on diagonals as they'll produce fewer blightsacs
8,8 - get down to the flag nearest to the bolders on the bottom row, activate it then kill self, each time you respawn move to the right until you can reach the top right flag. Then DL(DLx3ULDULDLx7URDRx3U) repeat brackets until you get through. Need help on 5,7 :(
:( so I finally complete all 20 levels to get to the expert level and it's bugged so I can't access it - instead of accessing the level it shrinks the character each time I enter the portal until finally I can see him no more
Great game. The second mode is a maze not survival - there are numbers besides some of the doors and they count down from 8 to 0. Once you've got to 0 the number of moves you took is written under the mode. My first successful attempt took 581 moves.

Oh, is that it? I haven't been able to replicate that bug, but maybe that's the solution. Thanks.
