more bug fixes and achievements

this game be hella buggy bro

Thanks to Cubemeren#0434 for discovering a bug when trying to go fullscreen during a game. This bug instantly crashes the game and makes relaunching it show something that looks like a 1x1 resolution? my guess is it corrupted the stored screen resolution. very weird.

Added a few more achievements:

• Goddess of Arachnids
• God of Thunder
• Goddess of the Wild
• Guardian of the Void
• ???
• Thanatos? (this achievements hasn't been fully implemented yet)

oke ty bye
