I really don't like rage games x)
The first time I fell I struggled so hard just to get back on the first platform, it sucked out all motivation for me to try further. I was also a bit put off by the controls, it felt that sometimes I was able to double jump and other times no.
What I really liked though is the setting, playing AS the poison is a fun idea! I also think it's great to put content warnings at the start.
