The kobold animations are definitely very cute and fun to look at! Animations or different poses for the dragon would be great to see if the game is expanded.
Menu design and play seem suitable for what you're aiming for. I like that new options appear only when you meet requirements so as not to overwhelm the players and keep them guessing. Maybe a silhouette of the next option could be a carrot on a stick to keep them playing to see the next thing? The start felt very slow for a clicker game, but I like that it promotes clicking various parts.
The monochrome characters are probably not the intended final style, but it sort of works. I think you could lean into it and have greyscale characters with lots of animations instead of fully colored ones with just a few.
It's a very promising start with all of the fundamentals in place. With a bit of tuning and more stuff to do, this can become a really good clicker game with a lot to offer!
