The first battle was hard but with your hints on the game page, I could make it.
There is plenty of work here and you can feel this when you play it. Love the genre! Great job!
Thanks for playing. At first I thought the first battle with all unlocked skills is normal, but then I realized it is normal only for RPG avid players, hence I give the hints at GamePage and option to skip.
The reference for "final battle like" as the first battle itself comes from old game Lufia from SNES.
