I am a new user of Construct, and I was exploring the functionality of this fantastic program.
While running the first tutorial I noticed an annoying problem that occurs when using the dark theme of the development environment.
As from the attached image, it is very difficult to read some keys. I would advise you to make those texts clearer, and maybe choose another colour for the hover effect (maybe a blue like the other buttons).
I am sure that the eyes of many users will thank you! :P
