There'll always be long lists of features we could potentially do, and we'll always be working our way through it. But for what it's worth, after all the things we've tried over the years, all the experiments we've done, all the PR stunts, all the blog posts written, and so on - in my view, by far the most effective thing is independent developers recommending us. If you want to help make Construct a success, merely talking about us on social media, showing what you're working on and mentioning the engine, or recommending us to others, I think is far more effective than anything we can do ourselves even if we threw a lot of money at it.
Another problem we've had in the past is people tend to disregard things we say ourselves. For example even if we show impressive results, people tend to have an attitude of "of course they'd say that about their own product". What independent developers say carries a lot more weight with other developers. So if you like us and want to help, it would be great if people who use Construct just talk about us! Independent feature comparisons, benchmarks and so on would be great too. Construct has tons of features and JavaScript performance is ridiculously good and in some cases it genuinely far exceeds the competition, but people seem to distrust us doing our own comparisons.
Also don't forget we recently launched a new affiliate program - so if you have a popular website, YouTube channel or whatever, you can make money from talking about Construct or helping promote it too.
