Really promising idea! I just really wish the "get to the spikes" part of the game would be more challenging - currently it doesn't add much to the game, since the green levels are trivial compared to the orange ones.
The artstyle and overall presentation was really good and the game felt very polished. However, the movement (mainly jumping) felt a little bit wonky.
I also really loved the way the first level serves as a tutorial - it contains no text, yet conveys the game's mechanics really well, which is a huge plus in my opinion.
Overall, really solid entry :)
