I was looking for some of the game development tools and then came across this tool. It allows you to make the platformer games and also some of the easy puzzle games. It's free tool and also you can export the game to the android. If you are into game and coding this can be a good start for your game dev career.
Create your own games with GDevelop: an open-source game creator. No programming skills are required! Quickly build and share your games on mobile (Android and iOS), desktop and on the web.
