-Text caret blinking but not having focus on the name prompt is bad, miscommunicates to the player.
-Audio is too loud by default. Like 2-3x louder than everything else on my PC.
-Going through tutorial. But I'm stuck? It says to buy elixirs from the shop, but I see no items in my list.
-I restarted the game but I see now. I thought the WEAPON, ARMOR, ACC, were related to the two icons below them, because my eyes were glazing over the icons themselves. I went to the Acc section and all is well. I may be dumb, but you could avoid that confusion by using colors or tab style UI so it's obvious all the icons are grouped with that specific section.
-Double click to remove item from hero inventory is slightly annoying, since click is how you equip/dequip. So you have to be careful, if you want to do that back to back. Why not use Rclick to move items instead?
-Having heroes exist on both sides of the 'inventory' for the embark menu is weird, inconsistent with the rest of the menus. At least, have an outline or some other indicator in the home box that says that hero is currently on the embark side too.
-I try to click on this node, and it just fails and moves the camera for no reason? Other nodes seem fine. [later] I beat the enemy on the right of this node, and I still can't walk there from that position.
-It would be nice if I could use keyboard, or hold some mouse button to allow panning the map camera, instead of moving my mouse to the edges of the screen.
-Battle mode. Clicking to drag the characters will fail if it's near their feet. Highlighted attacked enemies on selecting unit is neat, but I feel like it'd be better by showing all player/enemy targets simultaneously with line connections so you don't need to click around. Though, if you only have access to ~3 units it's less useful.
-If you click and hold a unit, then move you mouse off the grid and release(unit stops moving), then the next time you click it will teleport the unit last held.
-I finished the quest. I only used the elixir on my swordman twice. But, all my unit's elixirs are set to 1. Seems like a bug that decrements all those items simultaneously.
-With the inventory items being so few, I wish I could view all weapons simultaneously, and likewise for the other categories Armor and Acc.
-Unlocked research, why are there two Rings I listed?
Think I'm done now. Rough, but I see where you're going. Cool stuff, keep up the good work.
