Click the green flag twice! And if the cube just keeps jumping, click on it! This is like a mix between Geometry Dash and The Impossible Game, sort of. Just use the arrow keys, click the mouse, or press space to jump and don't crash into the sides of blocks. it's that simple. :) Please Don't comment complaints because at this point, it's your internet that's slow. I'm sorry I made an expansive and content-rich game for you.
Please note, this is Version 1.0 (The First Version) so it won't be the best. I'm currently working on Version 2.0, so please favourite and like so that I know you guys hyped to see 2.0! :) Thanks to @Will_Wam for the original project Cube Jumper!
