Nice game! I faced some issues in stage 2 like when zoomed out I could not see my troops and I can't move the camera freely to look around the map. Overall you have done a good job and I hope you will extend this game further.
Thanks for playing! Yeah there seems to be a bug specifically with level 2 where the camera starts all the way zoomed out sometimes causing what you said. Zooming in some will free up the camera again, I have zero idea what causes it lol.
