Our first 2-player, 5-wave game took 3 hours and 7 minutes to complete and we won. I think that the reason that we won is that I had very, very good luck when rolling the monster appearance die. I very rarely got a number above 6. I think in the entire game, I only rolled one level 5 monster and only 2 or 3 level 4 ones.
I can see an extremely difficult game if I was not so lucky.
Spot on time!
Indeed with the luck. Wow! That's exciting for a first run. ; )
Now you gotta balance it with the impossible "only roll over 6" version.
