Visuals:
- nice pixelart dragons, good job with the prompts, it's not so easy. I don't like the different pixel size between sprites and walls.
- nice battle animation (the enemy sprites are rendered very small vs the dragon character) but I think the camera moves too much, it's disorientating)

- add feedback for battle starting (even just a "Fight!" message)
- add numbers for HP/MP (maybe a setting)
UI:
- if the controls are mouse only, let each option in the menu align vertically to avoid moving the mouse too much (orders -> attack -> choose target -> fight, the last command requires you to move the mouse down for a lot of screen space)
- add more accessibility features:
- keyboard, gamepad controls)
- font size (extra score for UI scaling options)
Gameplay:
- enemies have too much HP. when I see 99 damage I tell myself: "wow that's a lot of dmg, it must be dead..." and then 3 more hits to kill it...
- combats are too slow (the long animations are in part responsible for this)
- first combat make the character level up 3 times.. that's a lot
Sound:
None... even basic free asset sounds make the game a lot more enjoyable.
Overall I think the game has potential but it's not very playable in the current state. Keep at it!
