The camera behaves strangely, keeps shaking. Personally, I don't like this tank style movement. You can fix these minor issues and make the game better.

Question, are you moving the cube using physics or transform ? And do you use raycasting? If yes the last one maybe have a look at implementation some interpolation which I think would help with the collisions and the "shakey" feeling it gives. Other than that the work is solid for the time given.

I had a difficult time with this game at first. Getting my head into, I looked over the controls and the crafting mechanic in the game. While I'm not against crafting survival games, that really felt like a forced element. I could forgive that as the idea of a crafting game fits snugly into the theme. However, walls and movement made me struggle the most. The "walls" seem to blend in with the backdrop... or are the backdrop? It makes it very confusing on where you are supposed to go. Once you start moving in the right direction, the movement is incredibly awkward.

I don't know a lot about Unity to help with any specifics but I would suggest spending a lot more time in the engine and polishing some of the basics. The movement was so frustrating that I didn't want to finish it. That mechanic talked me out of it. I'm not trying to be rough. Having a mechanic that does that is the thing you don't want. I would suggest taking some time to put some polish on the movement and the basics of the environment.

Above everything else, I hope you had fun and you learned a lot from this weekend!!!

Played both builds, Monday build was more solid on the control front but a bug that made the building connect to each other prevented me from progressing in a way.
Fun concept, exploring the world was a good time, wanted to see more crafting options.
This game definitely would appreciate some sound in it, even simple sounds will do!
Thanks for the fun!
