The wall-jumping at the vertical moving platform in the third room would probably be much easier if one could cling to it and let go instead of bouncing off and having to continue jumping towards it to keep on moving along with the rising platform. I could hardly get the first coin in the room, and forget getting about to the next one, ever...
Also, if it approached the platform one is standing on a bit more it would be easier to get at...
Movement with the game controller was fine, but couldn't use it for (re)starting the game...
