That looked fantastic! And the pixel art was so great! I loved the alien death animation. All the art was very clear but the crosshair, you should probably outline it, just like the gun to make it visible when aiming theenemies. I guess you know it by now, but numpad is really limiting! I use a tenkeyless keyboard as well but I grabbed another keyboard to test your game, it was the least I could do since you took the time try my game! Congrats! :D
