Clickteam [Official Site] are the company behind some really cool tools like Fusion, previously called Multimedia Fusion. They did an AMA today where a developer noted their Fusion 3 editor is running on Linux and other platforms:
Quote3) Our new engine is written in fully portable C++, and the editor already runs on Mac, Windows, Linux, and FreeBSD. The exporters already run on all of the above with the addition of Android and iOS. Implementing new exporters is much easier than in F2.5, so we're looking forward to making export options for as many platforms as we can!
I followed this up with a tweet to their official Twitter account and got a confirmation there too:
@gamingonlinux CONFIRMED!, But maybe not in the initial release but in update. Stay tuned!— Clickteam (@Clickteam) September 27, 2016
I've been a long time fan of Clickteam, and I used their older game creation tools Multimedia Fusion 1.2 and The Games Factory.
The difference between their tools and others, is the event system. Instead of needing to program every single line, you can stack up events and link them together to create a game. It works quite well and I'm pretty excited to give Fusion 3 a go on Linux myself to see what random games I can create for fun.
Their tools have been used to create games like Five Nights at Freddy's, The Escapists, Concrete Jungle and more. You can see a bigger list of Steam games made with their tools here.
It's exciting to hear that their brand new version already works on Linux, as it will be the first of them to do so.
They did a funny video to announce the AMA too:
