"Space bar to jump. Sorry it's so difficult, haha!"
I added a trajectory line so you'll see where you end up when you jump! I made the line stick around while jumping so that you can get a nice visual of the character following that path—I think it helps you get a feel for the timing too. I used clones for this effect, but the pen (with stamping) could have worked too. Thanks again to @midnightleopard for the original project, and 2017 me (*five* years ago! wow!) for the initial remix, which added sounds and music from the Squirrel Family games by Mateusz Skutnik. Update Mar 06, 2022: I added mouse controls for the jump button! So it should work on phones and tablets now. Also I fixed a bug where it would make the jump sound when you started the game by pressing space.
