First, the project I'm working on is made in Godot and it been a really long time since I worked with GDScript. (Required with Godot 4 to make a WebGL build)
I'm finished with all of the behind-the-screen logic as well as the main menu & the general visual design on the GUI side, but have yet to work on the core gameplay loop.
The game has 100% functioning saving/loading for both settings & player profiles menus, proper memory allocation & scene transition management, advanced graphics settings and some other stuff. (Also, the musics and use interface SFX are implemented.)
While my project is 3D, it has a retro feel to it because its settings is about space exploration in a similar style to the NASA Apollo program during the late 60's, but with a twist to it. There's a huge emphasis on its User Interactive graphics (GUI) as it's a game about resource and risks management, but at the same time it's a relatively simple game, gameplay-wise.
I'm planning on taking 2 days for the main gameplay loop and around 1 days for making the 3D assets still not done.
