So much to change
Like title said you need much thing change like;
-how much sp cost each skill
-barrier working (when i active it damage change from 10-20 to 2-3 what i take and cannot use on start battle)
-Barrier better will be if is for some rounds not forever
-Start fighting it will be nice if music start automaticaly
-If you have triple attack its impossible to see what dmg you did its maybe good idea to change to falling down number of dmg what you did and slower
-Maybe some more skills, and probably buffs debuffs etc like stun greneade or something like those for that armors can give other resist
-Reuse for skills, after first thing attack/defense you can spam rocket
-Fight is freaking ease enemy dont use any skills or whatever
-Difrent exprience points gained from difrent enemy 100 exp for final enemy and first?
