Main Idea
Cosmos, you travel through different dimensions and universes in space to find your way back to GD Earth.
Secondary Ideas
Must
In one of the dimensions Spikes are flipped with blocks so blocks kill you and you spikes don't.
In one dimension the portals are randomized but the gameplay is still the same like its ship gameplay but you're a ufo.
Optional
You get chased by aliens.
You become a spike instead of a cube.
Tradeoffs
I would choose time because you can't rush greatness
I would choose quality because the better the quality of the level the more people will like it and give thumbs up vote.
