i've already got almost all the games in the bundle... so here is my review
Hotline Miami: good game. May not be for everyone, its kinda frustrating, and weird but its original, challenging and interesting. i think its Worth it
Proteus: dont have this one. It is said that is not a game really, more like a music and visual experience worth trying
Little Inferno: this is probably the only game i want in the bundle. Heard is pretty nice but also short
Awesomenauts: if you like 2d platformer and you like MOBAs this game is great. I would be totally wasted playing this game if it wasnt because i played LoL for like 3 years, i couldnt take playing another MOBA. But awesomenauts is awesome. If you like it, you have MANY MANY hours of fun with this one
Capsized: l got this one but havent played it yet. seems ok
Thomas was Alone: some people liked this game, i was not interested on it.
Dear Esther: havent played it, but it is said to be good althought not much of a game but an experience.
In conclusion, I think this humble bundle has almost every indie game that was released for some time. There are still some gems that were not in bundles (FTL comes to my mind), but i consider this bundle to be a pack of Good games (not one single bad one)
