The first level (made by KobaBeach) is really easy with all the power ups lying around, but I like the backgrounds that are used. I think I remember seeing that second one before, but the hack that used it totally wasted it. The level I manage to fit in afterwards (the one made by Isocitration) was so well done. I guess the tremor stuff was in Isocitration's assigned box (the one with 3 resources to use in the level), and he managed to use it in many different ways. This might be the best entry, but I don't know.
