Post-Jam Minor Update

This minor update is to address the homing weapon. Currently, it is unfortunately too good, where it is capable to screen clearing fairly consistently even in late-game. The homing weapon has been tweaked with the following changes:

- Nerf homing acceleration and friction

- Nerf damage

- Nerf its lifetime

- Increase rate of fire

- Reduce its cost by 100

Other changes includes:

- Slightly increase starting weapon damage point

- Fix incorrect full heal max cost. It is supposed to be 10000, not 800.

- Slightly increase late-game spawning rate, slightly increase points to rank up as well to compensate
