There are instructions in the game if your like me and never read the instructions before playing but anyway- you automatically jump but press the up arrow to double-jump press space to use the shield this lets you attack the enemy without getting hurt the blue harts are the AI's health the red ones are yours
I got the idea from these toys called jumping beans they use a weight to make them jump about. Music and sound effects from Pixabey. All art from me. Enjoy (:
