I haven't played any of the games in this bundle, which is good, but from what I know of the games included and what's more my style the top of the bundle seems to be Halcyon 6 Lightspeed Edition that seems to take elements from FTL & RPG's and mixes it up into a very cool game. Mini Metro has "Overwhelmingly Positive" reviews on Steam and looks to be a really cool metro building sim game. Poly Bridge is a fun game that spawned off a ton of gaming memes as people tried to build strange bridges for cars to cross. I've heard good things about Soma and if you like horror games it's well worth checking out. If you want to pay $14 or more you can get SuperHot a really unique shooter game with interesting time mechanics. Rakuen & Keep Talking and Nobody Explodes are also included to help round the value of the bundle out. As with most Indie bundles a few games will be added later and as that happens I'll drop those in the comments.
I've limited myself to only purchasing 5 games this year and consider a bundle to be one purchase. That might be cheating but, it is what it is and I really do want to play Halcyon 6 quite a bit. Let me know if you plan on picking this up and if you've played anything in this bundle!

I haven’t played any of these either, but I’ve been wanting to play Superhot and Keep Talking and Nobody Explodes. Solid bundle!
