Sorry Ashley - but this plugin is simply not working for my game DarkBase 01.
I spent the last 2 days working on new builds (making sure to follow all instructions) but it's just not working for me.
Luckily, I still have my original build on Steam.
The original build is working perfectly, with no errors whatsoever - but also without achievements.
Maybe one day, all of Steam's features will be fully integrated into Construct without any issues (Construct 3 maybe? ) ...
but for now, I need to prepare to release my game with what I currently have.
