i just invent a supposed level for every enemy, it's more of a guide to show what lv should you be at the time, but nothing more.
and I'm sorry you don't like the HUD makasu, I'm kinda satisfied with it, it's pretty close to what I had in mind...
and although you're right about the icons, this is supposed to be a quick project, just to be sure I can actually finish a game, so i think I'll stick with the defaul ones, unless i find some better around, but I won't lose time drawing them.
