About & Contact


I'm Vadim (also known as YellowAfterlife), a programmer from Ukraine and the sole author of this website.

You might have heard of my work on Nuclear Throne, Nidhogg series (1, 2), or ongoing work on Rivals of Aether (see full list of projects).

I'm also somewhat known for my online multiplayer mods for Spelunky, Nuclear Throne, and Caveblazers.

Other projects can be found on itch.io (assets, smaller game mods, collabs), GitHub (tools and open-source contributions), BitBucket (smaller tools)

I'm familiar with a large number of tools and programming languages; most of the time I work with GameMaker (most of the games; primary subject of this blog), Haxe (most of the tools; I also wrote a Haxe->GM compiler), and C++ (native code for other tools).


I can be reached in a number of ways:

  • Email: yellowafterlife@hotmail.com
    I also have an ymail address that is occasionally used and a gmail address (yellow.ua@) that is even more rarely used.
  • Twitter: @yellowafterlife
  • Tumblr: yellowafterlife
  • Discord: YellowAfterlife#3735
  • Skype: YellowAfterlife
    Note: I no longer check Skype too often so you'll usually have to send me a message somewhere else asking to check Skype.
  • VK: yellowafterlife

I may be available for contract work.

  1. Could the base code be available?

    I’m trying to do something like you, I’m actually trying, but I can’t find a way.

    seeing that if it can be achieved, maybe getting the code before compiling can be useful in my self-study in the development of tools.

    sincerely a programming student

  2. I purchased your GMLive plugin a few months back. I managed to get it to work briefly. To cut to the chase would you be so kind as to send me a template project with the plugin working. So I can use that A base for my projects and don’t have to worry about screwing anything up.

    If this is possible it would benefit me more than having a to and fro regarding the mistakes I have made have you got that option checked etc.

    I appreciate your time. Thank you in advance.

    • If you are using GMS2 or GMS2.3, the setup process outlined in the video on itch page is all you have to do.

  3. Hi

    Ive got some idea to Terrasavr (Terraria Iventory editor)
    How about preview window of your character, this might help without running Terraria game to saw how gonna charr looks like if equip items.

    • Unfortunately that would be very high-effort – I would need to bundle hundreds more images with Terrasavr (some mobile devices already run out of video memory when using the tool) and implement a wide variety of methods the game draws equipped items/dyes. I recall that there was once (around 1.2 release?) an inventory editor that did show equipped items somewhat correctly, but it didn’t survive for very long.

  4. Hi Vadim, thanks for making the cool profile editor here, I’ve been using it a few times.

    That said, it’s suddenly stopped working for me for my Journey characters. Whenever I try to load a save for my main Journey character, it says

    ‘failed to load profile, error was
    RangeError: offset is outside the bounds of the DataView
    Was it a valid character file?’

    And sure, maybe playing the game has somehow corrupted that save while still allowing to play my character. What’s really weird though, is that this happens to every new Journey character I make too. I’ve tried making a new Journey character twice, once without entering a world and once with entering a world. Both times they have the same error!

    Do you have any idea what can be going on?

    Here’s my save file in case you want to take a look:
