Lovely concept, reminds me of some the dwarf incremental that have come out recently (not a bad thing).
Bug: running the game on Mac web browser shrinks the game itself into 1/4th the width and height of the Godot game window. This doesn't respond to changing browser scale. The prestige tree screen is full size though in the Godot window. Same on Safari and Chrome. I could only play it by changing my display resolution to something like 800 x 600.
Comments:
* It wasn't clear that you have to prestige before the dragon wakes up. I lost several prestige points by this, but the prestige point counter didn't reset. In the end I completed the game with only two prestige points so couldn't explore the prestige tree at all.
* after opening the barracks, then only making one warrior, then having the dragon wake up, I was returned to the game with a whole array of warriors that I'd never made.
