Thank you for your feedback! I am not at all surprised that you were lost at first. I decided to not spend any time on having a tutorial and instead just displaying all that information on the game page. Not realizing that most people will only see the jam submission page. Definitely a good lesson for next time!
And i completely agree on you with balancing. Right now it's all sorts of wack. But indeed not because of the damage numbers. Some players manage to defeat him just fine. I am planning on a small post game jam update to improve and fix some things. I am definitely going to take your suggestions into account. I want to give the player a bit more control over the units without just turning it into a RTS. Multiple spawn points or some simple pathing options could be great for this.
