I had a lot of fun playing the game. I loved all the little details, the presentation of the combat system, the setup of the music and the graphic effects... I've definitely learned a few things here as well for my own game. I wouldn't have a problem, to grind more monsters for level and stuff. I never found an accessory, but I had no problem using any skills or magic with Cynane, so to me the game didn't crash, but on the other hand I didn't hear any sounds from her either, so no idea if this was intended or not.
On the negative side, if this can be called so. The game was so cool, that I wished to learn more about the characters, but there weren't any more details or info to find. Some more characters in the city would have been cool. Teleport circles where you land with your character when using the teleport item.
I understand this game has been made in a short time and it's amazing... hope you will pick it up after the contest and maybe add a bit here and there, probably a perpetual system for grinding up the level if the player wants and a tower with even stronger monsters... and maybe a way to get the original form of the demon king back ;-)
Cheers!
P.S.: Funny thing, I noticed that this game would have a lot of voice-sounds, which I don't have at all. So it didn't crash, but I only had the combat sounds...
