Hey hey hey, thank you so much!
Watching this, I had urge to help you in certain points of playtrough :)
Great job man, and you bring me back hope with your comment. I love doing this so much, so when you say you liked it, that meens a lot for me.
And yes, the game is cruel. You have to play trough one door (with dying) but then you must done the other door in one take to open final door. And just a thing, when you collected coins, did you see a message on top of screen? I can not see it in your video, but it is kind of important. Every time you colect coin it should bring message that tips you or updates you on your state of yor progress.
Thank you again, and good luck!
