-- LUA Script - precede every function and global member with lowercase name of script

-- My save game script, version 1.0 (modified from Moshroom's script)

-- This script saves certain stats at end of each level so it can be loaded into next level
-- Saved Stats are player health and lives, cash, weapons collected and a mobcount variable
-- you will need to initialize the mobcount as a global variable and add a mobcount = mobcount + 1
-- to the mob scripts you use at the end when the mob is killed also add a cash global variable for
-- any money collected there is also a fourth saved variable for other use - haven't figured out ammo
-- or weapons already owned but not collected this level
-- Modify for each level end to show activeslot for that level - supports up to 10 level game
-- This is first level script

-- init when level first runs
