Fun! I got 100% in just over 11 minutes. It felt very good to play -- maybe a little easy to run into obstacles close to the edge as you enter a new screen, but not a big deal.
Biggest stumbling block was definitely the hallway with three saw blades early on. I hadn't figured out how to heal yet, so touching one was instant death. I tried jumping over the first blade twice before realizing I could walk under.
The puzzle with the two blocks took me way longer than it should have, ha. An interesting look at my own mindset.
Came across the hidden passages right away. Nice placement, I felt they were intuitive.
A little funny that the wooded area starts off with an intense platform ride, and then no danger after that, but I imagine that's a time-constraint thing.
Thanks for making this!
