The game is currently playable on Itch.io. If you'd like to look at the source code, or play the game in the Godot engine, follow the steps below:
Godot is a free and open source game engine which I used to develop this game. Here is a link to download: https://godotengine.org/.
On the right-hand bar, click "import" and navigate to where you cloned the repository clicking the project.godot file in the folder. This should successfully import the file.
You should be able to play the game now!
