The game isn't really a metroidvania but sure feels like a more crazy and chaotic Cameltry. I liked it. Like Sambi said, some guidance towards the end of each level would nice, but I understand the game's annoyances with getting lost and bouncing around uncontrollably were likely deliberate, something you wanted us to wrestle with.
I just think the game doesn't have enough variety in hazard types and mechanics to stay fresh for 20 levels, especially since they become longer and longer. After level 15, I got weary enough to pause it and took a break for a while.
