Launch the Quokka
As a University project we were tasked with making a physics-based puzzle game. For this we were supposed to use our own physics system.
I used one I had developped for C# before this project: Tank battle - physics engine.
We started with an engine called "GXP", I did NOT make GXP, it was made by teachers at my study at Saxion University As students we were supposed to use this engine to make games and we were free change anything we wanted.
