Complete the points of my Unity3D game: New Fight system

In my started game i need to fix and made this points: 1) the two controller right and left of the game have very hight sensibilty and need a better graphics of cursor on the left 2) now i dont know why i read an error in log and the controller if i run on pc, not working how on mobile 3)better simplex fight system: insert a solution that a enemy stop at small distance and go random punch or kiks and alternate stand position and random punch. considerete the possibility of n enemy in the sametimes. The enemy that follow the player in a range is done my me. now need this next step like this [login to view URL] 4) if i press one specific button i need that gun a particle system details: use the punch animation that at the end of the animation gun a blue energy small effect. subtract life to enemy and subtract a small quantity of mana to the principal player 5) if aurea level is maxim need to show a particle system of cosmos around character Details for the NEW fight system: 6) aurea charging if i press 2 buttons in the same time for example low punch + low kik and if are pressed the player change animation in charging mode with an auera araound it and add +1 to MANA level. if i press for long time him ad every second 1+1+1 etc... and if the aurea is not at 100% and i leave the buttons the aurea disappear and the char come back to stand position. If the aurea is at 100% we connect to the 4 point of old steps that is already done. the animation of the charging aurea is "Sword and Shield power up" from mixamo (the animation need to finish in base at the pression of the buttons or need to finish if mana is 100%) 7) press 3 buttons in same time for hyper. Change animation with an opportune animation and made a great particle system and subtract to the principal player a much quantity of MANA and subtract the enemy much life. 8) if enemy kik or punch me, him need to subtract me only life not mana 9) considerate the case that the player jump and made a kik or punch 10) use the particle system that i have download for aurea cosmos and punch effects 11) problems with the char that go up the step(stairwell) It gets stuck. the char dont is set correctly with the navmesh and 12) if enemy have 0 of life him need to go down with opportune animation of die. if the principal player go on it dont need to move the died enemy. 13) if player have 0 of life him need to go down with opportune animation and the game show an image with GAME OVER and comeback to main menu. questions: 14) its possible select stage and character in vs mode in menu? and select the main character in story mode? 15) its ready an level where is set the possibility to go underwater. now is necessary that the principal character change animation in swimming when touch the water at the middle and dont go down. if i press for example middle punch the char go underwater with the 3 animations are ready and are "swimming", "swimming to edge", "treading water" in mixamo site. the effects of refraction and underwater blur are ready. need to contemplate the case of the char go out of water.
