Click the crystals to collect gems. On the right side of the screen, you'll see three upgrades: Crystal Power, Crystal Speed, and Crystal Collector. Hover over them to read their descriptions. In the upper left corner, you'll see your gems and can turn music and sounds on and off. You can win the game in the lower right corner, but you'll need to earn 10,000 gems to do so. Press the spacebar to toggle the dev mode.
This is just an alpha version, so don't judge it too harshly. I made a remix for Henry6789010's game. Click here to play his game: https://scratch.mit.edu/projects/1233658181/ I improved the code and added a lot of new features. Play our games and enjoy!
