What is the best program to use for gameplay similar to Golden Axe but with higher quality graphics like Zombieville. I have concept art (still on paper, haven't traced onto any computer art program in case they doesn't work well with game program but I can easily modify the work to fit). Easiest way to put it is Castle Crashers art, movement plane and somewhat general idea of the combat (basic hack and slash melee combos, have other weapon system). Not really thinking of making a clone but more of a beat em up with inspirations from CC and others of the genre. Thank you in advance. EDIT: Maybe Unity?
