Not quite finished. Some explaining would do well...

Interesting. Although, it took me awhile to figure out how exactly to play.

To others: You choose the circuit at the bottom with V/B and follow it's pattern with "WAD" then press space afterward to confirm.

Nice concept and unusual, but interesting gameplay. More than several times I forgot to commit a sequence after I've already reached the brain, which was kind of frustrating. BTW, You should probably write the game rules here on the LD page as well, right now they are hard to find at the bottom of the page.

What a strange but interesting game! Took me a little while to figure it out

Hi. Interesting idea. Suggest maybe a level 1 or practice level with only one nerve to traverse... and instructions shown on the screen of game. Not enough visual/audio reward for completing a 'nerve trace' maybe?

As mentioned, took me awhile to figure out how to play, descpition is not clear.

After reading Raiyumi's instructions above, I was able to get a satisfying score. Pretty cool idea! It feels like frantically rushing around the controls of some great machine, trying to prevent a meltdown.

I would suggest making the lines a little easier to see (especially colourblind folks will have a problem). Also, if there was some ability to "recover" life, then the player would really have to balance gaining life and preventing damage.

Cool concept! Don't need so much more explanations in my opinion :)
