 ### `game_tick(mstime?)`
 
-Causes game to run for one tick. By default runs it and returns control to the program, but can optionally 
-accept expected tick length, in milliseconds. You can't use it to permanently change the game speed, but setting 
-longer commands with custom tick speeds can be interrupted via `/script stop` command
+Causes game to run for one tick. By default, it runs it and returns control to the program, but can optionally 
+accept expected tick length, in milliseconds, waits that extra remaining time and then returns the control to the program.
+You can't use it to permanently change the game speed, but setting 
+longer commands with custom tick speeds can be interrupted via `/script stop` command - if you can get access to the 
+command terminal.
+
+Running `game_tick()` as part of the code that runs within the game tick itself is generally a bad idea, 
+unless you know what this entails. Triggering the `game_tick()` will cause the current (shoulder) tick to pause, then run the internal tick, 
+then run the rest of the shoulder tick, which may lead to artifacts in between regular code execution and your game simulation code.
+If you need to break
+up your execution into chunks, you could queue the rest of the work into the next task using `schedule`, or perform your actions
+defining `__on_tick()` event handler, but in case you need to take a full control over the game loop and run some simulations using 
+`game_tick()` as the way to advance the game progress, that might be the simplest way to do it, 
+and triggering the script in a 'proper' way (there is not 'proper' way, but via commmand line, or server chat is the most 'proper'),
+would be the safest way to do it. For instance, running `game_tick()` from a command block triggered with a button, or in an entity
+ event triggered in an entity tick, may technically
+cause the game to run and encounter that call again, causing stack to overflow. Thankfully it doesn't happen in vanilla running 
+carpet, but may happen with other modified (modded) versions of the game.
