Cool concept, always impressed with 3D entries. I like the pixel size slider; Godot engine 3D with a large pixel size always makes me think of some alternate universe where Atari had 3D graphics. Great music that conveys an atmosphere of inevitability. A "real-time" mode where you only have a limited amount of time to decide which buildings to evacuate/reinforce would be a cool addition that could add some challenge, but the slower, thoughtful nature of the game as is fits just fine. Great work!
