You press WASD until you die; occasionally choosing an item from a list or opening a random upgrade box.

That's it; that's the game.

You also get different characters (starting bonus/item), and power-ups (slight stat alterations), but the core is just a 30-minute bullet hell one-life loop. Requires some tactical planning but not enough to make you feel at all stressed - is just a really nice, light game.
