Well done! Graphics and sounds are nice! I like the fact that you can straight up refuse to save the earth from the main menu and lose instantly xD
My only little things with this game is that up/down mouse sensitivity is up through the roof and that when in game, it isn't locked in the game window (I would often have my mouse move out the game window and I'd click outside when not in fullscreen.)
Apart from that, great game and great entry!
