Nice! I love this balance tweak! And it can be changed depending on how
strong we want it to be.

This makes it worth it so you don't wait till you're on ground

The impulse is fairly weak, but it has no cooldown (of course). As long
as you can reliably click on them, you can keep dragging them around.
This builds charge.

Portal now COSTS charge, rather than gaining it, so that you bully
people until you can build a portal.

Using FOV

You touching a wall does not do it. This encourages teamwork / using
your walls in clever ways to gain charge.

Also allow 100 walls, and removal of all walls upon death

Godot is a pain with source control and sometimes you've just gotta have

And Camera.project_ray_normal. This is much better

Also, levels now inherit a level object

Hero 0 speeds up especially quickly!

Hero 0: Remove cursor, allow wallriding (enable collision detection)

Hero 2: Move RepelHUD to center, ignore self with Area (gravity)

Accidentally put it in the wrong place before
