subway

Browse Source 
level: subway
  replaces gauntlet just before the final boss
    gauntlet moved to community map pool
  subway todo:
    add a few more stations
    balance difficulty
    find bugs

surface plasmons does 50% more damage
elasticity renamed nitinol because I bought some nitinol wire and it's neat
entanglement power up no longer shows guns or fields you already have
disabled minimal HUD for training levels
reaction inhibitor 12->11% mob max health reduction

spawn.bodyRect() now can add blocks mid level without any extra code
  I think I found all the bugs this causes, but let me know if any blocks added mid game aren't colliding

community map - clock update:
  visual overhaul,live lighting, remove pendulum overlap, move with pendulum if you stand in it, debris, trap exit only opens after completing the fight, moving elements now freeze while using time dilation

surface plasmons does 50% more damage
elasticity renamed nitinol because I bought some nitinol wire and it's neat
entanglement power up no longer shows guns or fields you already have
disabled minimal HUD for training levels
reaction inhibitor 12->11% mob max health reduction
spawn.bodyRect() now can add blocks mid level without any extra code
I think I found all the bugs this causes, but let me know if any blocks added mid game aren't colliding
community map - clock update:
visual overhaul,live lighting, remove pendulum overlap, move with pendulum if you stand in it, debris, trap exit only opens after completing the fight, moving elements now freeze while using time dilation

LoS
performance
calculate things that don't change when the map ctx is done

rewrite code for infinite range
how to use this?

custom level?
give it a dark back ground for contrast?
game setting?
applications
level that is dark, and you can only see LoS
boss that you need to avoid, probably requires a custom level
boss is a source of light
cloaking tech, or just replace cloaking effect
explosion graphic
mobs area of effect damage
maybe make a shared mob AoE damage function
standing wave graphic
consider increasing the base player horizontal movement
maybe only increase ground movement, air control seems fine
level: subway - a map that uses the train level element and line of sight graphics
stations
station theme ideas:
portals
teleport to far away rooms
slime
map elements that alternate between positions
buttons and doors
boss
spawn at the exit station? or at a random station? or at the station before the exit?
spawn on the station after enough mobs have been killed?
type of boss?
might need to make a new boss designed for this map: los and stations
small, quick, sneaky
do random bosses work?
I think
looks good with line of sight
background lighting for each room drawn in level.custom
no outdoors, no fall off the edge
slime
no small bumps
starting in a small room with a hole to the right with a short drop, like highrise or aerie
floating hexagons, like in reservoir, labs
ramping walls to jump over, like satellite
tech stubs should be a tech unlocked by skins
nitinol, tungsten?
maybe give another benefit?
defense?
make a shared variable for skin defense, since you can only have one skin
make a lemming that walks until it hits a wall and then turns around robotically
body or mob?
can't be killed?
