 The original game made use of the player's actual web browser to launch the game, but since then the NPAPI plugin interface the game relied on has been deprecated and is no longer available in most modern browsers. Both Retro and OpenFusion get around this issue by distributing an older version of Electron, a software package that is essentially a specialized web browser.
 
-The browser/Electron client opens a web page with an `<embed>` tag of MIME type `application/vnd.unity`, where the `src` param is the address of the game's `.unity3d` entrypoint.

 ## Gameplay
 
 The goal of the project is to faithfully recreate the game as it was at the time of the targeted build.
-The server is not yet complete, however, and some functionality is still missing.
+While most features are implemented and the game is playable start to finish, there may be missing functionality or bugs present.
 
-Because the server is still in development, ordinary players are allowed access to a few admin commands:
+Depending on the server configuration, you'll have access to certain commands.
 
-![](res/sane_upsell.png)
+For the public servers: Original has item spawning, the ability to set player speed/jump height, and teleportation enabled (default account level 50).
+Meanwhile the Academy server is more meant for legitimate playthroughs (default account level 99).
 
-### Movement commands
-* A `/speed` of around 2400 or 3000 is nice.
-* A `/jump` of about 50 will send you soaring
-* [This map](res/dong_number_map.png) (credit to Danny O) is useful for `/warp` coordinates.
-* `/goto` is useful for more precise teleportation (ie. for getting into Infected Zones, etc.).
+When hosting a local server, you will have access to all commands by default (account level 1).
 
-### Item commands
-* `/itemN [type] [itemId] [amount]`
-  (Refer to the [item list](https://docs.google.com/spreadsheets/d/1mpoJ9iTHl_xLI4wQ_9UvIDYNcsDYscdkyaGizs43TCg/))

-* `/nano_active [slot] (0-2)`
