Having said that, I gave the game another go after commenting and found that by just spawning knights constantly I can win every time :P

yea... balancing was certainly a feature that had to be cut for time as the technical side was... a bit hefty to say the least!
In my experience in testing, there are definitely some units that are stronger than others, but unit spam is definitely a strategy i noticed worked a bit too well, when I wanted to encourage a mix of units. That being said I have found you can win that way!
But I apperciate you bringing it up haha, if I had more time I deffo would have looked into balancing a bit more lol, as well as making units for explicitly counter one another.
