The instructions should be in the project! But just in case: press the arrow keys to move, dodge the grey spikes, and get to the orange portal to complete each level! You can also press the music icon to turn on/off music.
I made most of the code myself, but I did use some slight help from @aairfanf's platformer tutorial. Hope you enjoyed the game! If you did please give this project a heart or star, I would really appreciate it!
