fixedLevel 0 Visuals & Textures: I have fixed the textures in Level 0, addressing the negative feedback stating that the walls looked completely untextured. I've also reworked the post-processing so that Level 0 now closely resembles the classic yellow corridors the community knows and loves.
changedThe Bacteria (Entity/Monster): Fixed a major bug where The Bacteria could see through walls. Its AI has also been updated: it will now drop the chase more intelligently and continue to search the surrounding areas. While my work on this monster isn't 100% complete just yet, I wanted to deliver this significantly improved version to you right away.
fixedPerformance Optimization: Resolved an issue where death cinematics were causing performance drops and slowdowns on low-to-medium-end PCs.
