Aliens Go Home Run (itch)

Based on the ANIM•ACE game made for gbjam 4 ( bit.ly/1gS89Tv ), Aliens Go Home Run puts you in the shoes of Sally, a young girl with a passion for baseball. When she hits a home run so hard that it flies into space, it crashes into a faraway planet belonging to a mostly-hostile race, creating a crater in the process. Now, the aliens are invading Earth, and its up to Sally to save the day!
