Hi, so far I've only been a lurker, but something about your project really called my attention and decided to make an account.

I love all things roguelike/lite, and I love the premise of the story and the idea for this game, wish I could play it now!

So, regarding the sprites, the edits other members made and your edits all look more "pro" if you will, but there was just something so endearing about the original one, it's my favorite one! I think its expression fits the lore you describe better, and the other designs look more like the generic idea of a goblin, more villain-esque, whereas the original one fits a player character better, in my opinion.

If I were you I'd keep the original one and work on improving its quality while keeping its essence intact, and use the other sprites as enemies or maybe NPCs from the goblin town.

Anyways, this project is looking awesome, I'm a sucker for tilebased roguelike sprites.
Keep us updated!
