I realised that itch.io has no built-in way to contact me privately, and that the public comments may not work for everyone (especially among game creators, if they would risk spoiling something.
Please know that I don’t discriminate as long as what you are making would be fine to publish under itch.io’s content policy, so you don’t have to avoid commenting publicly for concerns in that regard, if commenting would be easiest for you).

Please include the problem description, version of the item you purchased and, if applicable, RPG Maker version (Help→About…), in your first message to me, especially on channels like Discord where I have to accept your request to receive further messages. This ensures your message won’t get overlooked.
In some cases, it can be helpful to include the list of plugins you have enabled, but this in not required.

That said, without further ado, these are the ways you can reliably get ahold of me:

• itcho.io comments on the respective item page (especially for “How to?” questions)
• Mastodon: @Tamschi@mastodon.gamedev.place
• Discord: tamschi (direct user account link, please log in first)
• Email: tamme@schichler.dev (template pre-fill link)

(I will keep this list updated in case my contact information changes.)

I should normally be able to get back to you within a day. If you contact me via email, please set the priority to ‘High’, and in case I don’t reply within three days, please re-send your message or use another contact channel (like the comments here) to alert me about your email.

Please don’t hesitate to contact me about any issues you encounter with my tools or plugins, including issues with usability or if anything is confusing or not explained well-enough. (If I don’t know about these smaller issues, I won’t be able to fix them, so really, please don’t hesitate.)

In cases where you contacted me privately but an explanation I give would be helpful in general, I may respond with a blog or devlog post instead, but by default will keep your identity private. (I’ll still reply to your original message to notify you of this, of course.)
Please let me know at any time, including after I post, if you’d like a small shout-out for posing the question.

Inquiries / Requests

If you would like to request a plugin, you can contact me through the comments on this post or the private message channels above. (Please adjust the email subject as needed.)

Please note that I generally will not do free requests. I’m open to creating custom RPG Maker MV plugins or small Rust programs as non-exclusive commissions.

The exception to this are engine bugfix and debugging plugins, which I can make for free if I think they would be generally-helpful-enough. Please note that I prioritise commissions over any free requests, however.

Additional support languages

You can contact me in English, German and French. I do not speak French well enough to write it, so in that case, please choose between English and German for my response. (I will default to English.)

You can also contact me in languages other than the above, but in those cases I will have to rely mostly on machine translation to read your message. I will reply in English and mention the translator I used, unless you recommend me a specific one in your message.
