I was hoping to get my time and death count, but they vanished the moment I finished the game. Just over 200 deaths, about 20 minutes to half an hour? I'm no Kaizo/IWBTG player but I do play a lot of high-difficulty platformers. This hit the sweet spot for challenging, but not masochistic - the constant taunts to give up felt unnecessary for me!
Sometimes the last level locks up with two lit triangles, presumably attempting to "shoot" eachother, stuck in place. This can ruin an attempt to get gold, as every symbol needs to be destroyed on that level. Has happened to me twice now.
