Very good work!
About the mechanics, I really like rogue-like elements such as permadeath and random generation, I think they enhance the replayability factor.
About the graphic, I like your cartoonish stylized trait, I think it works well for this kind of game.
About the musics, honestly, I'm a little disappointed: don't take it wrong, the background music is good, but I was expecting some variations, expecially because your map is divided in 5 different environmental sectors, so it would have been nice to have at least 1 different theme for every sector. Probably it could be your next goal for improvement.
By the way, about the save files, I've followed your procedure to allow Flash to store up to 10MB, nevertheless I cannot find a way to continue my saved game: when I click on"save and exit" I come back to the title screen, but when I click on "play" it makes me choose the difficulty to start a new game instead of continue the saved one... there's something that escapes me about that? Where's the "continue saved game" option?
Good luck with your next works!
Edit: I've tried to discover score mechanics and I think I've found a "bug": by playing different matches and losing on purpose after reaching certain goals, writing down scores on a spreadsheet, I've found that 1 hero level is worth 40 points, 1 completed quest is worth 20 points, 1 treasure found is worth 1 point and 1 monster slain is worth 3 points (about bosses defeated is more difficult to tell: by defeating a weak boss I've calculated it's worth 17 points to be a boss + 3 points to be a monter slain, but data doesn't match when I've defeated stronger bosses and won the game, so I don't know if stronger bosses are worth much points or if I gained a special boost because of Vorag). Then there're multipliers, and it's here that my data seems to show a bug: the problem is that multiplying all points for the multipliers it returns the same amount returned by the game only if leaving "treasures found" points outside the multipliers factors. The question is: it's done on purpose, or the multipliers should multiply all points gained? I think it's the latter, so I hope you can fix it, even if it isn't something very important, plus I'm curious to know if I have done my calculations well.
Edit2: I've just verified that by beating Vorag you gain an extra hidden x2 multiplier, then now I'm sure that bosses defeated are worth 17 points for being bosses (+3 points for increasing monsters slain count). Nevertheless the multiplier bug I've found still emerges from my data, so the question in my previous edit still persists.
