Hey man, first of all thank you for providing this nice little game! I have finally been able to play it a couple of times and I have some feedback:
1- I don't think many folks will know what you mean with "orthogonally" unless they research what that is ( I had to Google the term)... and then even if you get to grasp what orthogonally means, it is still not very clear how you can actually move through the dungeon.. do you have to go to the right and then down? Or down and then right forming the right angle? Can you zig-zag it? I don't know, I just can't seem to be completely sure what tile I can or should move to next.
2- This is way too difficult!... You have to roll pretty much perfectly every time or your stats will be too low and make it mathematically impossible to beat the boss when they get to roll 4d6 and you only 1d6. Don't get me wrong, I'm all up for a challenge but I absolutely believe the difficulty can use some tweaking.
