OK, so I played it.... I got to what felt like the end? Where I was running from a shadow or needle like sprite..... I was like 15 floors down, and I still had the robot icon? There were several of these things in later levels...like symbols or markings but also hard to decipher. The minimalism was good because it worked, I was intrigued to how this progressed the further I played. I used the fireballs only in one level and the robot I had like for 10 levels and never knew how to use it or where to use it.... either way.... Not a lot going on in general just a changing level that changed ever randomly with color or switches working or not working, or new enemies to avoid with some increasing difficulty. For what it is I am going with 3.5/5 Good job.
