Hi, I'm fine. Thanks for asking XD
How about you? XD
That's great for you to fix the game's problems so quickly XD I'll try the game later XD
For the friction's problem, I don't really know exactly why, but my guess is, the ground's colliders are not aligned perfectly. For example, can be seen here in the image, the green squares are the colliders. As you can see, it may cause collision when it collide with the player's collider. It should be aligned perfectly so the ground tile can be walked normally like walking in a straight line collider. You can use tile map in Unity for example, so they will be in a same size, and aligned perfectly. Other things that may help is changing the player's collider into circle or capsule instead of box, then turn on freeze z rotation. That way, when it collide with something like this, the round collider of player's collider will make it still walk able normally.
Hope this will help XD
Congratulations on finishing the game for game jam XD I'm glad you finished it so now, you can take a rest after a long time hardwork. XD
I think one of the way to do it is via Unity Tilemap.

https://docs.unity3d.com/Manual/class-Tilemap.html
That way the ground is placed on tile with same size, and aligned within grid.
