Hi there! I'm sorry for the delayed response. I've opening the file on my end and everything seems to be in order. To try to figure out the problem, a few questions: What OS are you using? Windows, Mac, or Linux? Is there any sort of pop up that appears telling you why the file can't be opened? Have you had issues like this with any other games on Itch?
Just to be sure everything is being done correctly, here's the proper steps for running the game:
- Download the .zip file
- Right click the zipped file and unzip it to its own folder
- From the "HeartFragment-[insert OS here]" folder, launch the game file; for PC this will be "Heart Fragment.exe", for Linux it'll be "Heart Fragment.sh", and on Mac you will go to the "Heart Fragment.app" folder, then "Contents", then "MacOS", and launch the file simply titled "Heart Fragment".
If you're still having issues, please let me know!
