Does anybody know how to fix the issue of the game crashing right after pressing start? It doesn't give me any reason why it does that...
There could be multiple reasons. Make sure that the game is compatible with your computer. To do this just right click the launcher icon and select 'Properties' and find the compatibility tab and make sure everything is in order. Antivirus could also be interfering. Some antiviruses destroy the whole game files meaning you have to redownload the game again. When you do make sure to first turn off your antivirus temporarily and if possible create an exception for the game after its downloaded (sometimes you have to restart your computer for it to take effect even if it doesnt warn you. so do that just in case before opening the game again). If not then you just have to keep the antivirus off as you play.
I cant think of anything else unless there is something running in the background, a virus maybe, that wont let you run the game for some other reason. If I recall correctly League of Legends would fail to download/patch a small part of the game and the game would close because of that missing part. Some computers weren't able to download the missing part even after many reinstallations. If this is the same issue you might need to use a different device but that is highly unlikely.
If all else fails and you cant find a fix online there are some youtube channels that narrate for you.
I'm sorry for not being able to mention this, but I'm actually trying to run this game on Android (PC died recently). Still, I'm so grateful for your help.
Fortunately, I was able to do some digging and found out that some VNs that run on Ren'Py isn't compatible with newer versions of Android.
Unfortunately, I can't do anything about it unless the game updates to suit the newer versions.
