I completed like till the Third Level, so basically the boss fight one, and considering that I reached that far, means the game is pretty good, all things considered. There are a few things that still have to be taken care of though.
Mainly the lack of SFX is very much noticeable, so a lot of things that should have very high impact, do kinda lose a bit of there Juice, but i am sure that's something you are already working on. The other thing that felt a bit off was the Character Designs, i imagine what you are trying to do was something akin to how different worlds have different types of people in it so they feel and look different, but that doesn't as much work in this, especially the Dronghur Leader he when compared to the Main Characters feel a bit too jarring.
Also the Main UI screen probably could do with a bit of Rework in style, especially considering I do like the style its in the Play Menu, so just anything that doesn't feel like the default font options of Godot.
The Gameplay itself I am not sure I have much to critique for since I don't play enough of these types of Games, but all the cards and the way they work feels like a unique enough compared to the other deck builder games i have tried before, and it all works in the Setting. Also while the first cutscene did feel a bit goofy, the second one was pretty cool, even though stylistically it felt way different then anything else in the game.
