The game glitched and took away my last key after I beat level 1. When I went back to try and get my pants I was out of keys. 3/5 since I had to run around naked the whole game.
This game is awesome. My best score was 98,000 after quite a few 30,000 games. The only stats you can raise without using the shop are Charm and Intelligence, so starting out high in the other categories is key to a better life.
The regular mode was pretty fun. Kind of a grindfest, though. Then Hard mode just became really unpleasant. You'd have to grind for a week to beat that. Maybe. I really don't think it's possible unless you get way, WAY better weapons. You can't upgrade your friend's spells anymore and your dragon can't get any better. I was maxed out on everything and had the best equipment at the time and I couldn't beat the "Blob Bonanza" level in Hard mode.
