Humble Bundle is currently running a unique game sale in a sense. The bundle is called the Humble Mozilla Bundle, and it includes only games that you can run directly in your browser, and not just in Firefox.
The list of games can be seen in the screenshot. Of the interesting at least Faster Than Light, in the rest unfortunately did not play.
A special feature of the distribution is also that the demo version of all the games can be tried out directly on the page. They are downloaded after clicking on the Play button and occupy a few tens of megabytes (Voxatron – 20 MB, FTL – 60 MB).
The games work well not only in Firefox, but at least in Chrome, which is the second recommended browser.
The regular price for these games with soundtracks is $104, but right now you can get them for a maximum of $8, or $1 without the last two titles. The bundle sale will last for another 13 days, and as usual you can get a key to activate all the games on Steam.
