itch.io

not yet but I really hope that the creator of this game will implement a co-op mode

1. you need to extract the ZIP file to a destination where you can find the folder extracted from the file

2. open the folder extracted from the zip file and you will find an .EXE file that says "pumpkin panic"

3. right click and click "create shortcut" (so you will have a quick shortcut to put on your desktop to quickly access the game)

PS. step 3 you can also skip it but you will be forced every time you want to play to open the folder you extracted from the ZIP file and click the EXE file "pumpkin panic"

I hope it was able to help you :)
