your main image is very good, when looking in the list it got my attention drawn, I liked the idea and the level design, there are some very good ideas there. I've also visited your page and played your bubble game from last year, its a similar approach, getting things from point a to point b, its really good for having built your portifolio.
I liked how you made every asset and build the whole game, also the enemies have different behaviours, which could have been tricky developing.
