My first LD entry , the quality of this is probably what you'd expect for a first go.
I've made many small test games in unity but i've never really finished them , this isnt an exception. I did spend as much time on this as i would of liked to , hopefully i have more free time next ludumdare. Ive seen screen shots of people pulling this type of game off much better in LD35.

There are three 'shapes' you can play as in the game and you can 'shift' between them. each one has some unique abilities.

Blue shape can jump 1 block and moves very fast but cannot push objects.
Pink/Purple shape can jump 2 blocks but it's tall and cannot fit in a lot of places.
Red shape cannot jump but can push blocks

A/D : Move left and right
space : Makes the player jump
up/down : Make the player 'shapeshift'
F : toggles fps

Edit:
Yes this "game" is super short , the room at the end is the end
