An update inspired by a Twitch stream

This update includes a few QoL updates and two real bug fixes

Bug fixes:

• Prevents improper starting of the Timeline Man easter egg hunt
• Prevents being shoved through icicles as if it's a river

QoL Updates:

• makes the water temple rivers more obviously interactible
• makes the grave scene more easy to interact with.

Unfortunately, while uploading this update, the demo disappeared? I'm not sure what happened.
