This is a submission for Mini Jam 74: Chaos.

Avoid getting hit by the spikes at the bottom of the blocks falling from above. At the same time, step on these same blocks in order to get above the finish line and win. (You can't win while in the air or on a falling block; you have to be on solid ground and above the finish line at the same time.) And most importantly - keep your HP afloat with a healthy dose of   s c r e a m i n g.

Controls/instructions

• A/X to pick a menu button and [Space] to select it.
• Press or hold A to scream in order to recover HP.  The capital "A"s (after the 9th lowercase "a") give more HP. Doing anything else or getting hit by a falling block interrupts the scream. You constantly lose a little HP, but you lose even more depending on how many times you've been hit.
• At the top-right corner and above the character, you can see which buttons to use to move left/right and to jump. The buttons are randomized every 60 seconds and they may be anything among X/8/P/B/[Space]. The space bar is a horizontal line, like a minus sign.

There's no official final level. The final level is just the one at which you give up (coincidentally, I got to level ⑨ on my test playthrough). There's also no way to pause or save mid-level, but the levels are short and you don't lose anything by dying so there's no need.
