Just finished
Wizorb, which I got in Humble Bundle 6.
Pleasantly surprised. I wasn't expecting much from a so-called "Brick-breaker RPG", but it finally was quite fun! Nice "old-school" graphisms, even on a 1920*1200 screen they were very enjoyable. Excellent handling of the game, which is what you expect from a brick-breaker game which needs speed and precision.
For the RPG part, well, there's a story, merchants, people to help, keys and locked doors, basic but well-made. So that was nice.
Only 4 hours of play on normal difficulty, but I found it perfect, longer it would have grown tedious, I think.
So, yes, I made a good decision in buying the Humble Bundle 6, hoping the other games will be as good as that one!
So far in 2012 :
