Psi-lunky (beta 1)

[hyperme]

Finally updating to what I'd consider a beta version. The major change going from alpha to beta is that Psi-lunky now saves scores in an external file. Ain't that grand.

Other changes:

+ Tunnelman B loadout added
+ Comet room, containing a new minigame
+ Chaos Zone now has it's own scores
* You need at least one win to access Chaos Zone and alternate loadouts
* Made Phantoms weaker, again
