NOTICE NOTICE NOTICE NOTICE NOTICE
In a few short hours 0.1.4.0 will be released. Now to each their own and this is NOT required, but you might want to consider doing a clean install.
First off, via File Explorer, find the folder where you have Holiday Island 0.1.3.3 installed. Within that folder will be a folder named 'game'. Within that folder will be a folder named 'saves'. Copy that folder and save it some where else where you can find it again. I copy and save mine to another hard drive, but your desktop, a USB stick, A floppy disc, doesn't matter as long as you know where it is and as long as it is separate and you can find it again. Now you can delete the folder Holiday Island 0.1.3.3.
Now using File Explorer again, look on your 'C' drive (usually the main hard drive) and find the folder 'User'. Within that folder will be a folder with your name. Within that folder will be a folder named 'AppData'. This is usually a hidden folder so you might have to turn on Hidden Files/Folders. Google or use Windows Help to learn how to do this if you don't know. Now within the 'AppData' folder will be a folder named 'Roaming' and within that one will be a folder named 'RenPy'. Lastly within "RenPy' will be a folder named 'Island - #########'. Your numbers may be different than mine. Delete that folder.
Congratulations, you are now ready to do a clean install of Holiday Island 0.1.4.0. Follow the install instructions and then copy your 'saves' folder that you originally saved into the 'game' folder of the new install and you are ready to go!
