I decided to go into a bit more detail about the software I currently use to make games, not just the main ones used to create them, but also the software I use to put it all together. I've listed everything roughly in order of importance, starting of course with...

Godot - Game engine

I could list many reasons why I use Godot, and why I dropped Unity after using it for so long, but put simply, it's because Godot just makes it so easy to make the games that I want to make, where Unity has too much complexity I'm not going to use.

Aesprite - Pixel art

Don't really have to say much about this, it's just the best free (if you compile it yourself) pixel art software out there, hands down.

Audacity - Audio editing

I've been using Audacity since before I started making games, it's easy to use, while also having tons of functionality, I've never needed anything more, and I doubt I ever will.

GIMP - Image editing

Much like Audacity, GIMP has been my go-to image editor ever since I found out about it, while I know many others exist, I've never needed anything that GIMP couldn't do, so I never needed to try any of them.

ImageMagick - Icon creation

This command line tool serves a very specific purpose for me, and that is the creation of .ico icon files for the Windows builds of my games. While I could easily use GIMP to do this, ImageMagick is far quicker and easier to use for this simple task.

ScreenToGif - GIFs and screenshots

This is an awesome piece of software that I wish I'd found sooner; not only is it the best GIF creation software I've used, but it also has an excellent screen recorder built in, and also doubles as a screenshot tool because it can save individual frames of the recording.

LMMS - Music

While I am yet to actually make my own music for games, I have used it for other purposes, and found it very flexible and easy to use, even more so than Bosca Ceoil, which is another common choice.

OBS - Video recording

Though I don't use it regularly (ScreenToGif covers the majority of my needs), I've tried countless other screen recorders, and OBS was the only one that didn't produce significant FPS drops while recording games, which is why I thought I should include it on this list.

And that's it, while I do use other software occasionally, such as Blender, Inkscape, GreenShot, and Bfxr, I don't use them enough to consider them part of my regular toolkit, so I didn't include them here either.
