Z/X/C only works on English Keyboards.
You also have Mouse control which is completely unmentioned anywhere. Why do you have dedicated Back/Menu Buttons? Why not have the menu open with back aswell? Movement feels good, Spriteart is alright mostly, Road seems a bit too even and straight, Maps are wast, flat and empty.
I can't continue/close Dialogue with close, only with accept?
Rocks don't have Z-Sorting correctly, and render behind the Player. Lower right Corner of the Forest in the Town is missing a part of the Tree. Thanks to the Trunks being smaller at the bottom rather then wider, it also looks like the Trees are rendering in reverse Order. Which in some Points they also definetly are, when you look at the Top of the Leaves.
I can't read the Books in the Libary for Tutorial/Tips? Sad.
Combat works, but the Sprites for the Enemies aren't on the same Pixelscale. Same with the HP/SP/Etc. Bars. You're making a Pixelgame, those should all be on the same Pixelscale. Effect Icons could also show on the Sprite more, rather then so far to the Side.
Layout makes me think I'm expecting 2 Partymembers and up to 2 Enemies more. If its always only the Player, why hide the Attack/Etc menu?
When I have no SP to cast a spell/Ability, it tells me correctly, but then moves me out of the Menues. I have to press Back again to get Control back, why?
Your Forest-map doesn't extend far enough up, I can see the grey behind it.
Savepoints should tell me that they also restored my Stats. Would also be nice if I got told how much my Stats increased per Levelup when I get one.
Is there no return because you didn't figure out how to keep Data consistent between Levels and thats why the Spikes are back up? Sorry if I'm doubting here, it just felt that Way.
The Archmage Fight was incredibly simple, but maybe I just overleveled. Balance seems to be off either Way.
Fun overall, if short and unfinished tho. Could be nice when done properly. Really needs to fix the Mixel Issues in Combat tho, and overhaul a few Sprites here and there. The Bars should be simple enough, a single flat Color for full/empty should be enough, but even with rounded Borders etc. it should be easily doable. Battlesprites currently are just upscaled Worldsprites it seems, but you're already in a very Graphic-lite Option with frontfacing classic RPG Combat, you could really put some interesting minimalistic 'NES-like' Sprites in there.
