While I appreciate the creativity around using a game engine for non gaming applications, this does not seem like a particularly good fit.

If most of your problem is 2d window/text stuff, the web browser is probably the best foundation to work with. UI and hud functionality in COTS game engines is light years behind what chromium and friends can do today.

Agree on Chrome being top-dog in this space. Electron would've been the easy (pragmatic?) choice. But the design decision was to use Godot and not create yet-another-Chrome-Electron app. It's certainly not pretty to look at in its current state.

This is something mainly working on it on my free time so figured why not see how far I could push things.
