Press space, up, or W to jump, and press down or S to crouch. Click the green flag twice, there are a few bugs if you don’t.
I remixed this from @mewtwocoder, and added some changes, like: - A day and night time system; this checks whether it is day or night and sets the background to that time of day. - A speed cap; this is so the game doesn’t get way too fast and become impossible. - An automatic score; like the original game. And more.
