I absolutely love the visuals and sound design. The gameplay is top-notch as well. Controls feel tight if maybe a touch on the floaty side with jumps but that's a minor thing.
Sometimes the obstacles hide each other too much (second room is an example of this) or they appear in positions where they simply can't be avoided. The main example of the second point is the first room. On more than one occasion, I had pistons close on the space I was in without having anything faded away enough for me to escape. Feels like bad luck more than bad decision making.
Cool game, though! Nice product for the available time!
