After collecting some feedback on Elysium, I significantly reduced the annoying things and adjusted the levels for a comfortable passage.
Players had a hard time with the vines, so the most important paths are now mostly replaced with something simpler.
The location-based puzzle of Elysium 3 has also undergone some changes to make it more clear and comfortable to create a path to the objective.

As for the shooting balance: many players complained about the shooting itself at the beginning of the game. So I made the basic accuracy and speed of bullets without improvements much more pleasant, and the accuracy improvements were replaced with a new bullet feature that allows you to partially pass through plasma shields, which will favorably raise the value of rifles and pistols compared to the “almighty plasma”.

Meanwhile, the work on the new sector is still ongoing...
Detailed list of changes:

• The basic firing rate of rifles has been slightly increased.
  
• The “accuracy” improvement has been replaced with “chance to penetrate plasma shield” for the Pistol, Rifle, and Olympic Rifle.
  
• All shooting parameters reconfigured, base bullet speed increased, base shooting accuracy increased, and “shooting accuracy” improvements are now merged with “bullet speed” improvement.
  
• The “long-range bullet split” improvement for the Olympic Rifle now triggers earlier.
  
• Elysium 1 - Simplified movement around the location.
  
• Elysium 2 - Simplified movement around the location. Removed friendly stingray, added additional enemies in the temple, and added enemy stingrays that activate in some areas.
  
• Elysium 1, 2 - added more respawn points so that when you fall, you don't lose the path you've traveled.
  
• Elysium 3 - simplified control of location elements, control panels moved for better accessibility, removed their duplication.
  
• The main lighting model is better adjusted, shadows should become less black, softer lighting of the environment.
  
• On many levels the lighting is better adjusted, on the South Station level, the lighting has been completely changed, with a golden sunshine.
  
• Island - the lighting of the day-night change is also better adjusted, and the fog of the location in good weather is reduced.
  
• Slightly improved graphics on some levels.
  
• Improved quality of the Volumetric Fog.
  
• The detection range of turrets placed by the player has been reduced.
  
• The “Esc” key now exits the hidden interface mode.
  
• Fixed the problem when the sprint is pressed before the start of the run - it did not work.
  
• The icon for changing the mode of the Olympic rifle has been raised above the reticle for better visibility.
