Quark
Quark is a fully-featured 2D game engine built as a final project for CPSC 4791 at Yale University. It includes an impulse-based physics engine, a custom scripting language, and mutex-controlled multithreading for subsystems running with different timesteps. Download demos here!

Engine Architecture
Postmortem
Looking back, I should have spent some more time building out useful
tools to assist in data creation. I had planned on building a scene
editor early on in the project, but later cut it out because I didn't
have enough time and decided to focus on my engine. While I am happy
with how things turned out, having to develop the actual game at the
end taught me to think from the perspective of the user as well, since
I realized that some additional tooling would've been more useful as
opposed to additional features in the engine.
That being said, if I had more time to work on the project, I would do
the following, roughly in stated order: build more assistive tooling
to make scene/collider/rigidbody creation as trivial as possible,
upgrade my physics engine to include fluid simulations for in-game
fluid animations, and add nice-to-have features such as spatial sound
effects, better text rendering, and various performance optimizations.
At a higher level, I would also like to build an input manager for
cohesive input tracking and a network manager/networking subsystem
for multiplayer games.
