I'll answer them!
1. Originally it released September 2022 (Unity Version)
Remade in Godot for Definitive Edition, which released January 2024.
Two final updates are being made to finish it: Part 1 1.1.1, and Part 2 1.2.0, which haven't released just yet (as of 27th July)
2. It hasn't been updated in a while due to previously University and then a 6 day a week job. I'm working on releasing the teased updates ASAP, so development can move on to other games such as my Pokemon one.
3. Unfortunately not officially.
4. This project is not monitised, and will be free for anyone to enjoy. People can donate to the creators (Glazed & I), or support us through patreon.
