That was a really cool puzzle platformer with a unique twist on the theme! I really like the idea you came up with and I had fun trying to solve the puzzles. Art and sound were also very strong and I love the speedrun timer feature for the more competitive group of gamers (like me haha)
The only thing is on the level where you have to drop down from high to hit the spring at the bottom, I think it would've been better if you didn't lose visual on your character just so you can see more.
Other than that, great job!
