I didn't understand the goal of the game but I had fun while playing it. I managed to make different pathways for the cubes to go into the portals as well as went around changing paths constantly to avoid collision as well as pick up objects. An addition of warning before the next block pops up would be nice so that you can plan your path ahead and don't have to do everything on the fly. Great job on the entry. A little bit more polish and I can easily see this as a great game!
