A very charming little game. Although I have to admit, I'm not sold on the mechanic, and let me explain:
Essentially, I felt like having to press Ctrl is redundant. Ctrl is basically your remaining available turns, and having to press a button just to be able to press another button is a little annoying at best. It took me a while to realize that I'm managing 2 resources, one being the toilet paper (which I get from poops) and the other being the remaining "Ctrl" (which I get by collecting toilet paper). Why not have the toilet paper give toilet paper?
In game design perspective, having these two resources is also redundant, because running out of Ctrl usually means you're dead, which isn't different at all than running out of toilet paper.
I feel like with a little more work you can create something more interesting than what essentially is snake with extra steps right now.
Good luck!
