My only wish is to have seen more on screen. I know that's a lot to ask as there is already a lot going on, but at a decillion or even by the time you reach the first trillion soldiers recruited, seeing the lower borders of the game screen completely empty feels underwhelming.
On that note, the fact that the champions overtake the entirety of the army's visuals once you get high enough is also a thing. If perhaps there were dedicated areas of the back line for the archers and mages so they remain visible, that would be cool too, because I loved seeing the mix of colors/projectiles.
The only real concern I found was the Reset button being overlapped by the Full Screen button. The secondary confirmation prompt prevents accidents but perhaps sliding that to the left a bit or hiding it within an options menu could be safer.
Other than that, the loop is sound, the knight interactions with the player are fun, and I spent way more time on this than I thought I would. Great job! Keep it up! 👍👍
