Thanks for checking out the game and your interest in it :3 I'm sorry to hear you're having the nw.js issue as well :(
I'm guessing you're on windows since you said you downloaded the additional files, or did you download the mac version and try the fixes someone told me to get mac users to try? I only ask cos I've read on Steam support before that the issue is more common with games made using Tyrano on the mac versions, but I was wondering if it's just as much of an issue on windows as well >.<
It's so frustrating because I'm not a super techy person (hence why I used Tyrano in the first place, haha) so when the issues are to do with the way Tyrano itself works, I don't know how to help anyone, and it really sucks :( I wish there was more support available for Tyrano in general.
I'm going to try and get a browser release out to see if that can be an alternative version for those who can't play due to the nw.js issue! I just don't know how long it will take me to release it, because I'm staying at my dad's right now and only have my crap laptop to work on >.<
If you do manage to get it working before I can find any other fixes to try, please let me know what you ended up doing that made it work so I can share the possible solution with others having the issue :3
