Hello, I created everything in just 10 minutes (cover not included) Just use your mouse to change the power of the shoot. If you put power on 15 the power remaining variable change around -15. If you are at 0 power remaining the game ends. Try to collect the crystalls and make the highscore!!!
made by me @Gamecreator_N another cool game: https://scratch.mit.edu/projects/702570550
