I agree with being prepared, and these days having an EULA is reasonable for a full game. Maybe keep it in game, but put it as a button to view it. Godot with GDScript does have an issue with being easy to steal as a non-compiled language. Using custom export templates with encryption does make it harder, but only so much. We do use the custom export templates option for all our games now. Those who are doing the ripping off of games aren't really going to care about any EULA agreements. Most are also likely going to be in places where any legal action will be difficult to take, and with or without an EULA, trying to get big companies like Google, Apple, or Steam to care about an indie claiming their game was stolen can be a pain. Each game having its own encryption key, and web exports using URL restrictions, seem to be among the best current options for indie devs. It won't stop those with the resources, but it will make it require more effort, which might stop some. Having a license agreement in the game is reasonable, and is something we should think of adding as well. We do have a basic copyright on the About/Credits page, but adding a bit more somewhere may help should any legal issues arise. Personally, I'm not ready for adding something that pops up on load, but having it from the main page might show up in the future in our games.
Honestly, the movement test's slippy movement was what drew most of my focus. I just retried it, and the tilt didn't seem too bad. The tilt was only odd in that I am controlling the camera with the mouse, so it changing was just an annoyance that was then adjusted as need by the mouse. Not doing 3D myself, why do you need 2 cameras for the workaround? Wouldn't you just have one outside the player that has its position adjusted to match the player's position every frame? Even with the dual (1st/3rd person) view options, I would think that you could have a single camera that tweens between the 2 positions as a smooth transition effect, rather than 2 dedicated cameras. Even with 2 cameras, Wouldn't they just have preset offsets from the player's position while moving with the player? Some day we will learn more about the 3D stuff. The kids really want to play around with it more, but it opens up so many additional details to work with, that we are sticking with the 2D stuff we know for now, and trying to have a solid base for the many aspects of game dev before opening a new can of worms.
Best of luck to you as well!
