Wait, are you able to kill the ground aliens? I thought we were just hurdling them... it added to the fun of avoiding that beam that's obviously trying to prevent you from jumping. I love the idea of the character only being able to shoot upwards. It adds to the mystery of the main character. Maybe he's focused on the sky aliens. Maybe he has no peripheral vision. Perhaps his left arm is in a cast. Whatever the reason, he's on a mission to shoot at the sky. In any case, it was surprisingly fun to play and the music and art are nice (especially that beam). Great job!
