Just because it's BiTwhatever's first time being bundled doesn't make it that special. A game like this will be bundled 5 or 6 more times before the end of this year.
There's no standout, this bundle is all just generic bundle fodder, and they'll all be bundled again at some point. Let's see, we got a couple of pixel platformers, a shmup, a low budget arcade racing/flying game, an endless runner, an "art" game, and a music game. All we're missing is the RPGmaker game and maybe throw in a shitty war-strategy game, or a space 4x game and you'll have the whole package.
