hey there!
Camera system is so much better and can automatically adjust itself for any resolution. This alone was great as Boomer had issues on ultra wide.
Particle system is awesome, works via a GUI and you get to see your adjustments live in game. In GM you had to do it in code and build the game every time you want to test it.
Better community support. Lots more tutorials and polished content. I hear GameMaker is now building a similar forum.
Platform support, it doesn’t cost more money to export to other platforms.
Anyway, these are just a few. I love GM, it’s really fun building in GM, but I wanted to give Unity a shot and it’s working out real well. I highly recommend it, especially considering it’s free.
Thanks for the support on Boomer!
Cheers!
