Enterable Ships, Gravity Overhaul, and Accidental Climbing!

Welp! I wanted to get a specific thing done today and I pulled it off!

Changes:

• You will notice I changed the name of the game on Itch.io to make it clear it's a tech demo.
• I also updated the description.

Now for actual game updates:

• New modular red ship model (Wings are separate objects, etc., this will allow for ship damage later).

• Smoothed out planet navigation and jumping/platforming, etc.
• More retro design for ship akin to galaga
