I’m impressed that you managed to export a Construct 2 project to WebView2. However, you need to note that Construct 3 projects have a completely different architecture, which means it has more features that Construct 2 doesn’t have. Unfortunately, I won’t be able to help you because Construct 2 doesn’t have official support for exporting to WebView2, and the architecture of projects made with it doesn’t allow you to change the size or position of the window (as far as I know).
