Polystar Dodger is a game where you play as a blue square, and your goal is to dodge stars of various different point amounts for as long as you can. There are twenty different levels to play, as well as a Custom Game with tons of properties and modifiers to alter.
This is a version of Polystar Dodger which does not have music in its levels. However, music files take up a lot of space, so this version not having any allows it to be played on lower-end devices that would crash when trying to play the version with music. The version of the game with music can be found at https://scratch.mit.edu/projects/416784291/. Further information about this game, including the list of updates, can be found in the Notes and Credits of the with-music version of the game.
