I have a few suggestions if there will be a new version:
-With the 'billboarding' option, there should also be the option to apply it to either the x or y dimensions, or both
-A very simple to use but effective A.I system. This is how it would work:
In a separate AI menu, you should be able to choose whether it is a good or bad AI.
If it's a good one, give the options to have it follow you, talk to you using the dialogue system, etc.
If it's a bad one, you can upload separate animations for it under the labels 'walk/run, attack, idle' etc
So it would be a very simple menu in which you choose the behavior of the AI, then select the appropriate animations for it
(The animations would have to be pre-made by the user in Blender or a similar program)
I understand this may be hard to code, but I think it would really benefit users of MegaKerma, especially those who want to make horror games with AI etc.
-Also cutscene support would be good, if possible
-And also (if possible) an upgrade to make the engine more powerful would be amazing, MegaKerma is so easy to use and has so much potential!
