I have actually ! From Stephen King, I remember the movie when I was a kid, it was very scary for me.
Thank you for your comment. I do agree ! I would love to have more time and talent to make obstacle fit to the current year as for the backgrounds.
Yes the spinning walls and bombs are generated randomly. For the "most difficult" level, the 3rd one, there is 35% chance that a generated enemy will be a spinning wall with an enemy generated every 0.8s. So Yes, it can happened that 2 walls are generated aside and it's kind of impossible to avoid them. It was pretty much ok because there are only 4 levels and the only one where you can have this problem is the 3rd. But you're right, maybe a checkpoint system could have been usefull :)
By the way, I've already told you but your game rocks... So poetic, very nice dialogs with fun also ! First time I explored to the right at the end and I was declared a coward by letting all my animals friends lol :)
