Sometimes I fell for a very long time and still survived, a few times I got stock in the platforms and couldn't move left or right, but other than that it played fine. Especially the delayed stop worked well as a platform mechanic.
The really good music and sound effects give this game a very strong mood, especially combined with falling far and then anxiously waiting to see if it turns into a game over or if the light is slowly crawling back up again.
I couldn't really focus on the messages once I got further down because I was focusing on not dying (again) and the text boxes felt frustrating because they are in the way of me seeing the next platforms. Not sure if that is on purpose.
