Devlog 7:

Finally added mass to the engine!
Before now all the particles had the same mass (just implicitly, so basically all of them had a mass of 1), making the small ones super dense.

Took so long because I had to migrate back to 2d in order to make sure the mass was working in 2d (everything was in 3d already so I actually added mass to 3d first), and had to update the 2d rendering for it to be able to render in 3d, but now everything (especially springs), is a lot cooler!
