should i toss him out?

hi guys, this seedling has been in this state for a week now, is he dead? :/ shes getting more and more tilted

Toss. Start over. Less water and/or add drainage.

stick it on a sunny windowsill and check back in 3-4 days

Keep it, don't over water. later repot and don't over water.

Does that eggshell have drainage?
I would really give up on the egg concept.

Don’t toss it. Give it some sunlight an less water an a few days.
