Super Crate Box

Anyone play this? it is a very small game but fun you can get new characters new levels and more! there are 3 levels and well the goal is to pick up as many crates as possible without getting killed by the enemies and larger enemies and really every time you reach a certain amount of crates from playing you will unlock the ability to get new weapons from crates it is a hard game but fun where do you find it? Find it on steam! My personal best was 28 crates
