Thats some commitment, respect O.o
Also thats normal, all enemies respawn each time you leave an area and re enter. I also managed to fix the broken turn display, ultimate and the wrong description and name. As well as adding a tutorial for the skill levels. To answeer what they do: damage skills get more power and support skills get shorter cooldowns.
In battle you also can aways look up what the status effects do that are inflicted on you, just press Esc when it's your turn. i will add a hint for taht as well. Hope taht could lift some confusion^^
After i tested it some more i will update the version with the current changes. I hope you still can enjoy the game!
