Oh man that music <3
The platforming physics is quite janky (default unity platformer controller ? It's almost impossible to make anything good with it...), and the link to the theme does not seem really interesting at first, but I'm glad I didn't stop there : the idea of having connected blocks that you can disconnect actually leads to very interesting level design, as there are multiple ways to get to the same platforms it leads to creative ways to finish levels, it is really enjoyable !
I think the bad physics and the fact that it takes time to understand the game will cost you a lot of points in the ratings, if you don't end up high in the ranking it doesn't mean your game is bad, just that it is not immediately appealing.
Oh and just a bit of nitpicking about the title menu : the Start button has the exact same font and size as the title, so at first I thought that the title was "Plat/Former Start" and there was only an exit button XD.
