RPG Tsukuru 2000 cheat codes:
Walk through everything (test mode)
If you get stuck while in test mode, or you need to walk through any
solid objects, simply hold the Ctrl key down and walk through it.

Change Variables/Switches In Test Play:
While in Test Mode, by hitting the [F9] Key, you will be able to
access a debug menu that allows you to change switches from ON -> OFF
or from OFF -> ON. It also allows you to change the value of any variable.
This saves you the trouble of going in the game, and back out to change
the commands.

Increase Text Message Speed:
While in Test Play, at any time by holding the SHIFT Key, the text speed
will be greatly increased. (This is useful if you are trying to skim
through lengthy scenes).

Reducing Lag:
You may notice that in events that have a lot of complex coding, or
events that call others with complex coding, tend to lag when the
game is played. This makes gameplay very annoying. To prevent this,
insert a Wait of 0.0 seconds before and after the Call Event or group
of complex coding. This will remove lag almost entirely. Making gameplay
much more enjoyable.
