Well :
1. The "upgrade sword" from the shop didn't do anything for me
2. I don't know if that was intended but you can actually roll the dice twice just by pressing Z quickly after the first one if the result is in your disadventage
3. Even with this cheat I've found I couldn't beat the boss this should tell a lot about the difficulty of the game
4. Hire me as a damn game tester I am so good at this ! :p
Anyway I enjoyed the game especially the simple controls
