Does the app have a popup warning (for epilepsy)? Might be important if it's not already there (just based off my video game experiences!)

The Windows Apps store?

The hardest parts for stuff like this are configuration (set up, AKA getting started) and deployment (the export, AKA finishing). Specifically because it involves text-based tasks. GUI-based tasks are "easier" for everyone to process because they're "prettier". Hence why we have fancy graphics/layouts now instead of 100% text interfaces, which would drive most people insane (I tried going without graphics for a week, command line only, stopped being fun after the 1st day or so).

I should probably respond to you by PM... Unless you created another post related to this? I don't want to go off on a tangent and flood your AMA with technobabble lol.

I need to use the keytool command from the Oracle JDK (I installed this) but I have no idea what that means.

Not sure what you need cryptography for... Sounds related to app signature/security. When you download an app it has a "trusted secret code" that your phone can decode/check to verify that "Apple says it's safe" (I'm really over simplifying here). Disclaimer: I haven't built a mobile app but my day job involves Java/web technologies (that run on mobile devices + PCs, even PlayStation although it's not officially supported/tested).

Apparently Godot is a brand spanking new product (released last month), which would explain why I haven't heard of it. Is there anything specific you need from it? It sounds like overkill for what you are making.
