I have made a mod for this game that is easy to inject and uses a separate program to operate The Handy. Per-scene device configuration can be done dynamically by changing the configuration file.
Download
Get the mod and device control program here.

You will also need to purchase and download the game on DLSite. I am not sharing the game itself, please support the people who created it.
Install
Unzip the game itself into a folder somewhere on your drive. For the purposes of this guide, we will assume it is named gaman2.
Unzip the contents of the mod zip into the same directory that the game is in. This means all of the files should be right next to gaman2.exe. The important ones to verify are there:
gaman2.exe: the game itselfgaman2-handy.exe: the device control programAfterInit2.tjs: the modcurl_silent.vbs: a helper the mod uses to interface with the device control programconfig.json: the device control program’s configuration
You may need to install curl, but I think most windows machines have it available out of the box nowadays. If you get any weird errors then make sure you have curl installed and available since the mod needs it to communicate with the device control program.
Setup
Open the config.json file in any text editor of your choosing (eg. VS Code, Notepad, etc). The only thing you are required to change is the device key. Change "key": "<key-here>" to use your Handy key.
Optionally, you can configure settings for the device that will occur on different game events. By default the important ones are covered, but you can customize things if you like.
If you want to react to new events or debug what is going on, you may toggle debug and trace to get increasingly more information about what is happening in the game.
Run
First, ensure that your Handy is connected to wifi.
Next, start gaman2-handy.exe. This will open up a console window that runs the device control program. It will print out some information as it goes, but you can minimize the window or ignore it.
Finally, open gaman2.exe to play the game. If the mod is installed correctly then you should see a popup that says “http_hook.tjs loaded” to confirm that things are working. If you do not see this popup then return to the previous steps and try to install the mod again carefully.
It is also worth noting that this mod does partially work with the first game in the series as well. However, I have not configured things for this game so you will have to update events. It also has a different post-orgasm routine which I have not investigated or hooked into so your mileage may vary!
For people interested in the source code, you can get it at the following link. The only required dependency is Bun.
