12 Labours of Hercules IV: Mother Nature - this one was pretty much like any other 12 LoH title. A simple resource management game with a little bit of story told at the beginning of each stage. Nothing special, but it was a good time waster during work breaks.

Agatha Christie - The ABC Murders - As an Agatha Christie fan I put off playing this game for a long time because I feared the voice acting would disappoint, also I kinda had to due to the name of this challenge.
I never watched a Poirot movie but I read all the books so I created my own version of him in my mind with a certain accent and tone of speech. I do that for all the characters in books (is that weird? I’m sure I’m not the only one) or games that are not voice acted. Also poor voice acting is a big no, I abandoned games before because of that.
To go straight to the point, Poirot’s voice actor did a pretty decent job but for the fact that he didn’t say “little gray cells” as in the subtitles, but “brain cells”. I’m not sure if the script was written like that or he just decided to be a smartass. Kinda insulting to the fans in my opinion, it’s one of Poirot’s mannerisms. Blasphemy! But the game itself was ok. The puzzles were more on the easy side while still requiring a bit of thinking and clue searching. I didn’t need to use a guide. The story can be enjoyed even if you never read an Agatha Christie novel. One playthrough took me 6 hours, I played it twice for the missed achievements.
It was okay, I’m just mad at the voice actor.

Brushwood Buddies - now this was a hidden gem and the best one of the bunch. I never played a “crafting game” before. Really, all you do is craft. I’ve seen people comparing it to Doodle God which is a bit more known.
You get different biomes which spawn specific objects. Every level has a certain item that needs to be created in order to move forward and they get progressively more complex. Some critters (buddies) will join you and you have to keep them happy in order to be able to craft. The trick is that some get sad or happy when you destroy or craft an item so you have to find out what their likes and dislikes are and manage them.
I had fun playing it, especially hunting for the achievements. I like it when developers give players something fun to do after finishing the game.

Californium - I almost added it to the pile of abandoned games due to horrible, laggy mouse control.
I think it could be called a walking sim but with a bit of object searching. You play as a writer who shifts between different realities. Each chapter takes place in one and you have to find and activate hidden symbols to, uhmm… tear the reality, I guess I could say. But these are not always in plain sight, and this is where I almost gave up on finishing it. Some would spawn while you are facing away and you would have to turn away quickly and click on them. I tried different sensitivity settings, turned off anti aliasing and in the end decided to put the graphics on low. That did the trick, but took away from the enjoyment of Californium’s strongest point, the visuals. Pity.
In the end I didn’t fully understand what I just played but it was still an interesting experience. I will play again on February 12. I don’t mess with my clock for cheevos
