Thank you! There isn't anything special after that, or multiple endings, so if you managed to get into the core you won the game. Hopefully we can expand it after the game jam version, then you'll see a lot more things ;)
That's too sad since there is potential.
Maybe have some super expensive upgrade for an "Auto Defense System" aka aimbot+2 turrets on both sides so the base defends itself.
and have some huge tree or whatever grow after getting enough plat orbs, so after so and so many collected orbs, enough oxygen is produced so no suit is needed in the dome.
so after you get both things, you have created a new sweet dome home for you, where you will live for the rest of your life, no need to hope for some core :-)
