the left and right arrows are to move and the up arrow is to jump. the objective is to collect ten coins and then go to the portal. as you collect the coins they will move to another spot and some spots are harder to get to than others. if you touch the spikes you will respawn and the ladders give you a boost. Hint: the coins near the portal are worth two coins. the 1,2, and 3 keys are to change your map.
I watched a Quick video to make gravity for the player because I had no idea how to do that but the rest I did on my own. my main problem was that my player was too big and I was struggling to make levels but then I thought I don't have to make the screen bigger I just have to make everything else smaller, and it worked!
