Nice job, this feels very fleshed out!
I had a Warrior, eventually bought all the tier 1 gear and got halfway towards level 2. The only dungeon I was able to fight in was the left one, and couldn't take on the bat enemy successfully yet. Best I could do was 2-3 slimes or 2 rats.
My feedback is to make it more visually obvious which character is attacking for those who don't read the battle log.
Also, the king's speech bubble about jobs, quests and dungeons has those words highlighted in a way that I expected a tooltip when I hovered over them.
The effects landing on the target are good, the information on the screen is clear, and it performs well!
