It goes by the name of Super Crate Box, and it is available on Steam right now in exchange for no money.
Not free-to-play or freemium, just plain old free. How can it be much more cheap than the $3 title Wizorb, you ask? In fact, this game is completely free. It is also in the arcade style, but it is much more challenging and much more cheap. This week I would like to recommend a game which you may not have heard of. In the first post of this series, I praised Tribute Games’ much-maligned Wizorb for being a high-quality recent example of a cheap, challenging, arcade-style game.
