Cool concept! My first run through was successful. I bought the fighter gear, cyclone strike, and boosted my ATK, DEF, and Agility to 20 (and my HP and MP by 5). I'm glad I saved my potions and ethers for the dragon, which made him pretty manageable.
The humor was great, particularly the ending. I did admittedly do a lot of save scumming to make it to the end, particularly through the penultimate room.
