For reference, I'm playing on a PC Douche and I just X'd out of the screen. I played for a few minutes and here are some things I would address:

1. In the town, Tonic and Potion are mixed up from each other on the "buy" and "inventory" spots, that would lead to purchases of the wrong item I bet.
2. When I died, I got a game over screen, and could do nothing but X out and reload the game.
3. When I enter the town or entered a battle, the main map window would vanish and just the new window would appear. I'd rather the main map window would stay up.
4. During battles, that screen takes precedent over anything and it can't be minimized.
5. Ability to use items outside of battle.
6. Health/magic replenished at level up?

Edit: This was all before your latest update.

I just downloaded the latest version, I haven't played since the first version....the starter mobs are kicking my ass! Okay, grabbed the knife and things are going better, tried the sword and I guess it didn't stick.

Adding notes as I play:

Level up music is sweet!
I want my HP/MP replenished with level up!
I want to name my character.
I want to be able to minimize/move the game window or sound off option.
I want to move my character with WASD keys.
First "boss" music is sweet.
First boss kicked my ass. Fuuuuuuuuuck.

After reaching just level 2, the mobs are generally stupidly easy, other than the bridge boss, who fucked me up.

I don't mind going to the Inn to save, I think people nowadays are more used to being able to save anytime though......haha, this reminded me of playing NES when I was younger, and my dad would say to turn it off, and I'd tell him I just have to save, and he'd go nuts because he wanted it off right away, that dude cost me so many level ups.....asshole

Reset button maybe?

I think herbs are killing me if my hp is low when i use it?....ahh, the enemy is attacking before my herb kicks in? I feel like if I'm using an item, it should be the next action taken in the battle.

I don't think all changes are sticking everytime I load it, based on the gold being only 100 sometimes, and 500 other times.

I have to buy, then upgrade the knife twice for it to take any effect, then when i reload a saved game, it is wiped away, so to reload a save would require a lot more gold for testing purposes, so we can get a weapon again.

EDIT: Main map music is good, but the loop point is too abrupt, it needs to flow back to the beginning more fluidly.

Maybe I'm trying to fight him too soon, but that boss crushes me pretty quickly. I lack patience and if I die I have to start over because the weapon can't save.

You can use the inn with no money, money goes negative.

Mobs after the first bridge are a bit harder for sure, I really meant around the first town that mobs are really easy really soon, but I guess how soon they become really easy depends on how long you plan on making the game . I'm also using the knife upgraded twice, that may not be a realistic option at the start as the game refined.

I think battles need to move a touch slower, I can spam through a battle in a second. Some sort of flow like player attacks, attack effect, description of attack, mob attacks, effect, description....I guess a good question is, how long do you envision a play through of the game to take? That would help me gauge some of the timing nuances and if I feel they are appropriate.
