I am addicted to this game. However, I have be a bit disappointed it had only 20 levels. Hopefully there are several difficulty levels. I am looking forward for any update that would add more “content”.
Hi! I'm working on update at the moment that has a bit of extra content. There are lots of difficulty levels, including curse mode which you can unlock by beating the full game on hard : )
I have some plans to add more content in the future but I cannot promise anything.
