This game gets a surprising amount of praise for being a mediocre Asteroids variant. Ignoring Sinistar's comical lack of chill, the gameplay loop consists of shooting at rocks that don't degrade in any way to collect resources for bombs you'll need to defeat Sinistar. The only thing keeping you from doing this is an occasional ship that shows up. That's it. That's the extent of the danger. The entire loop just feels like it goes from 1 to 11 without anything interesting in between.
