I think the best way to grow your Construct skills is to make a clone of another game. This is not for earning money, but only for educational purposes. I want to create a turn-based strategy game like Civilization with Construct 3 in the future. It's a really difficult task, and first, I should start by creating something simpler. So, I've decided to make a clone of a very special game.
Revival is a Civilization-like strategy game published on the J2ME platform for old mobile devices over 15 years ago. I spent hundreds and hundreds of hours playing this game when I was a teenager. It's a great honor for me to recreate this game using Construct 3.
This project will be published on Scirra Arcade. I will also be sharing the source code. I hope this will help you find some ideas that you can use in your own projects. An important detail is that I will not be using any JavaScript code or any third-party plugins or behaviors for my project.
Wish me luck ;)
