I don`n know what to say. On one side is a very original concept, and you input good native tutorial, on the other side this mechanic is very frustrated.
When I see few "suicide blocks" I want exit the game immediately, because the essence of platformers on reaction is opportunity to pass level the first time. I think, if I see that I have to die many times is controversial pleasure.
However, this is still one of the best games on this jam, good luck!
