Really cool game, looks amazing , and seems like you have really put in the work, really nice.
I must admit tho, it is a bit of a tough start. Maybe it is because I just woke up. I will try again and ask my partner to try too as she might do far better than this for me. Sadly tho, i must admit, because of the difficulty, I won't be a dependable player. If your goal is to go for a hard game, then you nailed it, nothing wrong with that, in fact some people will prefer that, however from a player base, I would suggest adding another world that is slightly easier. I am only suggesting this because your game is beautiful and I think everyone should at least try it, but if it is impossible to get past the first section without a bit of brain power then the exposure might suffer. Again if it is what you are going for, really cool, but if you want to build a bit of retention...
Good luck, not that you need it ;)
