Let's get jigi and climb the tower of snails! (Snail-free option added) [ENDED]

Have you ever wanted to see some snails stacked on top of each other? I did.
A traintower, behind a simple sgtools rule, behind a jigidi. Ends on 14 of June.

I've decided to add alternative puzzle for our molluscophobic friends: https://www.jigidi.com/solve/102inlk2/nest-in-a-stump/ Uh, hope you don't suffer from fear of bird nests as well?
I made it with more pieces since the image is more varied, but I'm still not sure if the difficulty is equivalent. If anyone solves both, what do you guys think?

List of games: 8-Bit Adventures: The Forgotten Journey, Back to Bed, Ballpoint Universe - Infinite, Hexoscope, Little Nightmares Complete Edition (Region Restricted, sorry, China and Japan), Plazma Being, Prismatica, Swapperoo, Swordbreaker The Game, Unknown Fate.

Some SNAIL music to set the mood.

PS: WARNING Last time I did this, jigidi was occasionally having problems with showing completion message. I recommend registering an account so that your progress gets saved and you can try a different browser or device if anything goes wrong.
