I have not done any serious programming for this game for now. I use almost only construct events and behaviors, and scripting in js only for level data. I'm a javascript (vue.js) developer 9-5, so it would almost as working if wrote game logic in js. Construct behaviors are awesome, just a few clicks and you have a fully functional player character. It has a downside that the free version is limited. For example, I have not found a way to add the same behaviors to more than one sprite type (in paid version this is done I think by grouping sprites in families). This is the reason I have just one type of bird. I'm thinking about looking for some walkaround in js thou.
I'm 100% sure I will use Construct in the future, mostly for prototyping, but it won't be my framework of choice. For real games, I would need a full edition and I find it too expensive for a product with such a small community. I mean there are tons of nice tutorials on youtube, but searching for answers for something more specific was hard. I would really recommend it as a game engine for someone who never wrote a game before.
