I thought we could use any Game Engine, But nope, So I don't think that I will be able to participate in this jam
Sorry for the confusion. We would love for you to try our app, though :) It is definitely a different experience from using a custom game engine, but we plan to iterate quickly with updates supporting advanced features!
So, I just want to know that can we use any other engine?
Unfortunately, you have to use our app. Sorry!
Thank you for your interest, though. Please do let us know if you have any suggestions or feedback.
