This is a little game that I made in hopes of creating a decent platformer (I failed). All you have to do is use the left and right arrow keys to move back and forth, use the up arrow key to jump, and the down arrow key to shrink. Don't touch red, as usual. Get to the green, blue, or purple circle to advance to the next level.
UPDATE: I added the falling spikes and made the game harder, thanks to the helpful comment from @MaciD2 (if you have any suggestions, please comment them in a respectful way)! I got the idea for the shrinking from the project "Pen Hero" by @GameNoob, and the script is from @djpro's tutorial. Otherwise, this is all me! There are probably a few bugs or glitches in the program. Please tell me if you find one! Double click green flag, please!
