ok, the ai dosent have to be TOO sophisticated, i mean normle enemys should just have walking (sometimes jumping/flying) (idk) it depends, it could be like mario enemys, walking back and forth. it could be ↑ but chases you when in view range. it could be anything, i would say just do the easyest thing to start with.. i have planned 1 enemy i drew out, but its not done yet. (i love my new 2ds)
