The latest Humble Weekly Sakle invites you to pay what you want for Gaijin Games’ Bit.Trip Runner. If you cough up a measly $1, you’ll also score Symphony and Sequence. Pony up a whole $6 – woah, big spender! – to score Beat Hazard Ultra and the excellent Audiosurf and Retro/Grade. Some DRM-free, Linux and Mac options are available, and soundtracks are included. As ever, your purchase price is split between developers, organisers and charity. This deal ends March 27 so get on it.
