Enemies new weapons and leveling
new enemies with special abilities. 1.ninjas invisible to an extent but can be vagely seen then the become visible when they attack. 2. Robots who can fire lasers and such. 3 dragons Fireballs,nuff said. 4 giant spiders in which can shoot webs that slow you down like when your in sand. 5.giants i know this sounds a little to skyrimie but giants would be pretty cool.
also leveling would be better than just sitting around with three hp and give your character weapons you can only use at certain levels
New weapons like an axe dagger bow and arrow and more
Many of this would make the game 2000X better even know this game is 3X better than any 8bit game in the world :).
I added a leveling system today, check it out! http://blog.8bitmmo.net/2013/07/leveling-system-added/
