The theme of the latest Humble Weekly Bundle is "monochrome" - every game features a black and white aesthetic.
Pay what you want for The Bridge (Linux, Mac, PC; Steam or DRM-free), Closure (Linux, Mac, PC; Steam or DRM-free) and Dominique Pamplemousse (Mac, PC; Steam or DRM-free).
Cough up more than the average - $4.09 at time of writing - to receive NaissanceE (PC; Steam or DRM-free), Betrayer (PC; Steam) and Oquonie (Mac; DRM-free).
Finally, slap down $10 or more and you'll also receive Neverending Nightmares, available via Steam or DRM-free for all three platforms.
A couple of the games come with soundtracks, and Dominique Pamplemousse even includes sheet music.
As ever, you choose how proceeds are split between developers, organisers and charity. This week's beneficiaries are Direct Relief and Special Effect.
Head on over to Humble Bundle to take advantage.
