Congratulations in completing your first jam game, it being an RTS as well and doing it on your own!
The RTS elements worked rather well. The message was helpful to know how to play. The background did give it this mystifying atmosphere to the game. I really liked the idea of the cells defending the body from unwanted cells.
After defeating the enemies, I was not sure what I had to do until I zoomed out and saw the enemy base. While zoomed out it was difficult to select a single unit as I had to drag to select just one unit which was difficult as the units were tiny.
The enemies did not feel that much of a challenge, as I just sent my brawlers and destroyer cells. Although the Enemy base was tough, that is for sure.
I was not exactly sure how the Worker cells actually worked. Do they just exist and create resources?
Overall, a simple RTS game.
