buildA | 5/17 hot-fix update

last update was very rushed. sorry for that. 

today's update includes:

• all previous preview enrolled levels are now accessible 
• negative level -0 preview is available. (is registered as -1 due technical reasons)
  
• terminal behavior has been changed. 
• added sector transportation object in level 1 and 4
• level the end no longer transport you to next sectors
• bug fix: after parsing jerry, catatonic state will force-unlock at level transportation
• bug fix: level 1 timer would continue after  transportation
• bug fix: level 1 ceiling decors had spawn issue
• bug fix: I didn't know this whole time that all the wallpapers was indeed upside-down...

known issues:

• some of the sectors are very clippy.
• staircase in level4 gets covered by wall spawn, expect for those spawned on outer wall.
