Looking forward to the full game, though I wanted to point out that Flash Terrain dice is totally broken in this version. I've attached images of my turn 1 and 2 below. I gave up after floor 300-ish as it wasn't getting harder fast enough.
The parts of the insane combo are:
* Mark of the Chosen One
* Bullseye
* Chocolate Muffin
* Flash terrain dice
I had 4 flash hollow terrain dice in my final deck of 9 dice (plus 4 attack and one block - all flash and hollow). At the end of turn 1 I have a space which gives +164. Before I attack on turn 2 (thanks to no damage from the Chocolate Muffin) that increases to +271. The +271 appears to be applied before the Bullseye bonus, meaning each dice was doing well over 500 damage... and I had 4 of them. Even then, I had 546 block on turn 2 before the enemy had a chance to attack.
So yeah, flash terrain dice are OP.
