I've been looking for some platform examples, and I found Hello Engine for GM8

Or this SMB Engine

It's pretty neat although I'm not sure if they can be classified as "engines", but a good example if ENIGMA can execute it.
I'm trying hard to understand how it work, but I think it's not a bad thing if ENIGMA comes with many pre-built frameworks for Platformer/RPG/Shooting etc....
popcade, I have made two attempts in the past to port that, as I remember it relies on variable_global_exists and other global variable access functions, we will need to wait for the new compiler I believe in order to get it working, but its definitely on the list of games we plan to have working.
