Things I would want in a 1.0:
purchasable Enchanter/Disenchanter in town
boss monster(s)
more control over portals (level selection, feature selection) or maybe a reroll function with the expenditure of experience
more terrain types
more quests/storyline with the main NPCs
recruitable minor NPCs with controllable inventories
strong attack for spells (hold Q)
hitscan lightning spell that just does raw damage (or maybe slows the enemy?)
advance/rewind stage buttons or keys for sex scenes
