@@ -42,6 +42,7 @@ Some of the **gameplay features** include:
 - **No codes of censorship, flags, furry mascots or similar political bullshit**. This is just a game.
 - **No "modern" bullshit such as OOP, meme design patterns, scripting and similar nonsense**.
 - It is **absolutely and completely public domain free software with ZERO conditions on use** under CC0, it is legally more free that most "FOSS" software, there is no copyleft or credit requirement, you can do ABSOLUTELY anything you want with the project. This is a **selfless project aiming for no benefit of the creator** (include any non-finacial benefit as well), this is made purely to bring more good to the world without gaining any advantage for self.
+- This game has **PURE SOUL**. No Unity or Unreal, no "retro" imitation shaders, no assets from a store. This isn't an immitation of a 90s game, this IS a 90s game.

 =========== GENERAL ==============
 
+- make the U-ramp map taller due to new physics
+- replay format should probably record game version
+  - also there should probably be some version system that says version of
+    physics vs version of everything else; replay could only record physics
+    version (maybe just two or three chars?)
 - on 1st map the camera is obscured by the wall at the start, fix it somehow
   (not the best first impression)
 - culling is very slow now, it showed that distance bailout can accelerate it
