This isn’t a download issue, it sounds like you are’t familiar with how to extract and run a game downloaded from the internet.
If you use the itchio app, it will automatically manage the download for you: https://itch.io/app
Alternatively, since you already have the file downloaded, you can follow these instructions:
- Locate the downloaded ZIP file on your computer.
- Right-click on the file and select “Extract All…” or “Unzip…” from the context menu.
- Choose a destination folder where you want the extracted files to go and confirm the action.
- After extraction, open the destination folder and look for the game’s executable file (usually labeled as
.exe
for Windows) to start the game.
Make sure to extract all files before attempting to run the game, as running it directly from within the ZIP file can lead to errors.
