Really nice concept! The idea is original and fits the theme well. The controls are a bit stiff and lack polish, in my opinion. Also, it is possible to get stuck; for example, if you fall and don't have a configuration with a platform to climb again, you have to wait until the configuration change to your advantage again. I got a bug where the platform spawned around me during a jump, and I just got stuck for a while. I found it fun and enjoyed it, and I would have loved to have more levels :)
The presentation may be improved a bit, maybe with some screenshots, a logo, and a well-designed theme. (I specify it since it is one of the criteria of the notation)
Well done :)
