Great entry.
I've seen some other people comment on short coming so I'll say some ideas I had:
1- deck starts out too defensive, I think you want 4 attack markers to start and customize it from there.
2- Buff is *really* bad. Perhaps if it also buffed your heals/block, but it runs out too quickly (expiring before you can do anything if you roll a 1)
3- perhaps roll two dice on movement and let the player pick one so they can get to a shop
3.5- If I finally get to a shop, let me buy more than one item. I had a ton of gold and wasn't able to use much of it.
4- I'm not sure how you set up dice, but there is an exploit where you can jump after you've done your first roll, as the dice are moving over to do the second roll. This lets you reroll your number, though you'll have to jump again to roll action even though it also changes.
I really enjoyed this game though.
