I like threads like this. Thanks. It's my first game jam!
In my case, I rarely use Unity. I mostly program without game engines in Java, C# and also making websites in html, css, javascript. So I had to learn a lot of things about Unity:
- The animator graph and animations
- The tilemap with the tile palette and the grid
- The pixel perfect camera
- Camera shake
- A little bit of new unit UI I did not know about
- How to get pixel perfect fonts with Unity
- The rule tiles (Saves a lot of time)
- How to make top down player movements
- How to make a dialogue system
- How to make a spawn system
- How to place things in-game
That's pretty much it. You can see how it turned out, here is my submission

PS: The link to your game goes to Half life 3, I don't know if that was intentional XD
