This is my 40 Hour Game Jam entry. You have to escape the level in under 10 seconds. To do this, you have a couple of moves which can be combined for tremendous speed.
Theme: 10 Seconds, Escape
You can for example Dash into the ground then Slide and then Jump for a lot of horizontal velocity. Or you could Dash into the ground WITHOUT sliding then Jump for a more 45 degree angle.
You can also do this with wall jumps for various effects.
