I decided to go for Gamemaker this year but gave my pupils the option to use Construct2 as I had played about with it and was impressed. The games also look really good. I had a level 5/6 class this year and four pupils used it at level 6 and one pupil used it at level 5. The rest of the class used Gamemaker.
The games created look really good and the pupils got to grips with it quite quickly. They taught themselves how to use it using the tutorials available. There are quite a few tutorials available on youtube so whenever they got stuck and were looking to do something e.g. create a health bar, I was able to put it on the big screen.
There are limitations to the number of events etc… that one of my pupils ran into but as long as the game isn’t overly complicated it shouldn’t be too much of a problem.
You can see a comparison of the different licences here:
I’m planning to use the free version of Construct 2 as the main software for CGD next year.
