I enjoy puzzle games like this one, and I'm pretty impressed on how you built it! Presentation was really good, and I enjoyed the music as well. I do personally think having a bigger level would've helped on having more paths to reach the goal, and that way you could've made it so some paths are over 10 seconds long. In my experience I couldn't find a single path that took me over 10 seconds to go through.
Nice game! This is a really good base you have, and I think there's a lot of potential to build from it.
