That is less than the typical Indie game, which needs about 3 GB.

Leave at least 6 GB free: games need headroom to unpack updates.

A reinvention of the cave-flyer for players who love games of skill. You control an extremely responsive ship, which opens up new possibilities for speed flying challenges, puzzles, and bullet hell scenarios. This game is set at 1980s difficulty--Survive it if you can.
