Hii!
Thanks a lot for playing the game and sharing feedback! :D
I agree with both of your points. Due to the tight deadline, I couldn't spend much time with the map borders. That said, I really like your interpretation of the blue field as a sea rather than just an invisible wall. Would be fun to make the goons drown.
For the civilians, although you weren’t able to delete them directly, I hope you still had some fun making them panic when you hit them! There is a deletion mechanic where if you knock an enemy into a civilian, the civilian gets deleted, so you have to be careful about where you send enemies flying.
