Thanks a lot for trying out the game so soon and giving your honest opinions. I will definitely try to implement a minimap. But in my opinion, the main element of the game was the very limited field of view, so the minimap would not fit into that very well. I personally found a few features missing too, so I will put those too in the next update.
edit: I was just watching your YouTube videos, and I am extremely grateful to you, but I wanted to know from which place in the map did you clip. I personally never encountered that particular bug before.
