Fantastic first attempt at a game! Definitely keep it up.
To help anyone who tries to play in the browser and the page throws a warning, try this:
1. Download the zip file.
2. Unzip it; I just unzipped it into my Downloads folder. Open that folder up.
3. Right click in the file explorer window near the files and select "Open in Terminal"
4. Type "cmd" and hit enter.
5. Now type: "python3 -m http.server 8080"
6. Open up a web browser and navigate to: 127.0.0.1:8080
7. Game should pop right up.
