Use the arrow keys to move, a common feature in most of my projects as they are platformers that will require you to move to win. Collect the stars, something I haven't yet featured in any of my mini-games (with the exception of Chase the Star). The stars don't really do anything special, they're just bright additions to an otherwise dull moving game. I will probably be making more mini-games in addition to my main quest adventure games, so be sure to be on the lookout for more of those! Also I counted how much code this required and it came to a very not-whopping 37 blocks. I admit I was expecting it would be more but thats sometimes the way things are. Have fun playing the mini-game, and keep on the lookout for The Leap Through Space: A Sci-Fi Platformer & RPG, coming soon to a Scratch account near you! P.S. Again, sorry I didn't add the W/A/S/D keys as they are more work and just genuinely something I didn't want to get into. I know that sounds shallow but its th truth.
