Great dungeon crawler game. Love the style and music, but it still has a few very odd kinks and possible bugs.
FYI:
Crit Damage = Attack + Critical (that's it. So, Attack is better to get since it applies all the time, not just when you crit.)
Stun is the damage you'll do when you hold down the left mouse button and you get the burst. It stuns enemies so they wont move or attack for about 1 sec. (Stun damage appears to also apply on the first attack after charging, and it counts as a crit.)
Also, keep in mind what element you currently have when you pick up your next one. The result is usually a combination of the two.
Still no idea what that little crown means.
I love how easy the game is to pick up. You really don't need to know much to figure it out, and things are kept super simple. Problem is, it's TOO simple. I mean, a crit only adds Attack and Critical together. This means getting ANY critical [damage] is pointless, only critical chance matters because all weapons have at least a little critical. And while you could argue that stun might be worth focusing because it hits everything around you, you're going to get tons of stun from 3-4 other pieces of equipment. Higher level equipment should ALWAYS have better stats than their lower level equivalent. Equipment drops are WAY too common, and just get in the way. Bosses should always drop gear that is at-or-around the level of what you're wearing... the list goes on.
TL; DR: Don't be so sloppy about the mechanics. Don't make stats that can be easily substituted. Just like every other dungeon crawler out there, don't bother give us crappy gear compared to what we have. And put a little more effort into conveying what the stats actually do. (Put a pause menu for options, and possibly a glossary of terms or something.)
I wouldn't have said so much if I didn't care, good luck in the future! =^_^=
