If you like portal-likes and can tolerate some jank and a lot of programmer art, this is an interesting and mostly-enjoyable game. I have two primary issues that made me annoyed:

1. Each room uses a single material for nearly all surfaces. This, combined with the lack of any significant lighting, means that there are very few visual queues as to position and orientation. Two rooms are particularly bad. One is a very dark sphere that can be seen in one of the store screenshots, while the other is a rats nest of cubic pipes that introduces a new mechanic/control.
   
2. I spent quite a while wandering that rats nest before poking through the controls menu to discover that mechanic. If there was a prompt for it, I missed it.
