So I decided to learn Unity.
The best way (at least for me) was to make a similar project I made when I started learning Unreal. So a simple physics based ball roller is what I went for.

Here's what I've done so far

• Used the newer input system to map movement and reset to start functionality

• Working with textures and materials

• Applying Physical Material

• Terrain manipulation

• Foliage placement

• Simple hud and end screen

• Post processing

• Made a spline mesh (not used here)

To help myself a bit, I made a similar project in unreal using a rolling template, although it was quite broken and I had to manually fix that first.
This kinda helped me to pace myself by helping me work on one thing at a time. I would do something in unreal like make a hud to just display the level name, then I would try to remake that in unity.
