Most of the fights are nowhere near challenging after you get a hold of better weapons, and when you are in dungeons where you come across chests that increase your life points or mana by 10 :P
The monsters in the training ground needs to be tougher as you level up. It is pointless to fight against what seems to be level one monsters that barely give you any experience points or money for that matter.
I don't know why, but despite the fact that there are other games of the same genre, I think this one is the most entertaining. I am not sure if it is the fact that a toilet is involved, or how the dude on the seat does not look entertained.
Finally defeated the dragon after playing the games 6 times! It worked with only 2 adventurers (one at level 15, and the other at 17). Making them run around in circles at the last stage really helped, as well as making them fight as many monsters as they can in other levels. ALWAYS get the chests and experience point books to achieve the hard badge.
There are some issues with the adventurers going to tiles that are not connected to your path whatsoever. What is even more annoying is that after they go to unconnected tiles, they go straight back to Floor 0.
An easy way to kill Bugzilla is to use the stun grenades. After losing to him a few times, I used 3 of the stun grenades in one battle and he was easily killed with using only one medic kit.
There is a glitch with changing roosters (sometimes). You can have two of the same person on your team, which is annoying when you need to another member.
Disliking the battle with the 3 Black Blades A LOT. How on earth do you win when they heal themselves 70 HP in every round once you lower their health to around 25% of the original --;
