Wow, this was surprisingly entertaining. I wasn't expecting that much, but it was really good. I think the main reason I liked it so much was because it just had a cheery feeling to it. I appreciate the graphics and how much detail was put into them. That one level I can't get past is Level 11. At first, I thought I wasn't going to like this because I didn't know how to double jump.
I was able to get far even without doing that! It's just a pleasant game with all the lulling music. It still has the occasional zombie, but it's still very fun. I thought I had played a game with this same name before but it was "Recursive" something by Armegalo. I'm glad to know more about recursion.
