You can use whichever you like, Godot was actually mentioned and linked to in today's livestream, along with Construct 3.
Oh good to know, Thank you so much for responding! I completely missed the livestream >_<
can i use gamemaker too
Yes I think you can :D
Any game engine is allowed – According to 2 responses about engines I read here in the topics of this game Jam, so game maker should be fine :)
