arrow keys to move on pc, use the joystick thingy on the bottom left for mobile. Simply duplicate the ground sprite and add about 50-40 to it's scroll x position. to make a red ground like at the start, just change the ground to the normal red color. If you want, there is a Username block that you can input your username so that you can see the variables when you press the flag. For the barriers, I couldn't think of how to make that work, so I decided to make it a range. just simply add your own block to the range and which direction you want it (5 for the left side, -5 for the right side.)
This is just me trying something new, and it turned out ok. It is just a platformer, so it is made to be remixed and completed. feel free to add stuff in.
