I really love the art style, especially the parallax of the multi-layered city in the background. The concept is neat, almost like tetris meets endless runner. The music is a bop too so loved that.
I would say, the inverted x-axis controls do make it hard to get into. You build a rhythm but it always feels just that little bit unnatural. One big thing I would say is that I found it very difficult to open doors in time as it seemed the click area around them was fairly unforgiving.
I'm not sure if they are set as buttons or if its a raycast hitting a collider, but I would expand the clickable area/collider either way so that it will accept a click that's fairly close to it. Especially with the often very short time you had to click on it, a little bit of extra wiggle room for the click area would go a long way.
