Quick OP impressions:
Krafters
... is basically just a tech demo atm in which you cant do much other than aimless digging. The current state of the game is nowhere near the screenshot in the OP. The above screenshot shows everything its currently offering.
Labyrinth of Keys
... is more interesting than it seems at first, but its also kind of unfairly punishing. Its one of those games that tasks you with exploring its mechanics before you can explore the world (which I love), but it devolves into random trial and error and unfairness a bit too often. 2 examples: You walk around with a key, that key allows you to read books and open exactly ONE door. If its the wrong door, you can continue exploring, but you'll miss out on all the other books, which makes finishing the game impossible because you need the hints from the books. Now if you carefully walk 5 minutes to a place, only to step on a switch that randomly shoots out a spirit that robs your key.. and you need to walk all the way back there again, only to notice that the door you managed to open was a dud... then this game starts to ignite even my anger. Another example would be a room with 30 switches and you need to press the ONE right one. If you dont, its back to the beginning to walk to that room and try again.
Not very fun design, even if the core gameplay mechanic is intriguing.
Landslide McQueen
Incredibly short and simplistic highscore game that doesnt have much to it other than its artstyle and the wacky novelty of the "gameplay". In my opinion it doesnt quite work as a highscore game either since there isnt really room for skill/improvement.
Lost in Her Eye:
Another very simplistic game in which you only walk around and click on a multitude of objects to make them go away. Feel free to correct me in case I am missing something, but other than the incredibly fast disappearing novely of walking on someones eye.. not really interesting.
Luftrausers:
Easily the best of todays bunch. The free browser version isnt representative of the full version. Different challenges, equippable plane parts, more... everything. The controls are as tight as in the free version though. If you think the free version controls nice and thats a style of gameplay you'd want to spend more time with, the full version Luftrausers will keep you busy for a good amount of time because nailing the controls and maneuvers feels very good and satisfying. Warning though, it becomes quite hard.
Mammoth Gravity Battles:
A game about shooting a variety of weapons at targets that are affected by the gravity of different objects in space... as an asynchronous SP/MP game. Initially this demo started out with the well known puzzle style formula of "you have x shots, hit targets", but once they throw in some AI enemies, this game becomes way more interesting as you will need to figure out the correct gravity affected trajectory of a shot and move yourself within the 2D and 3D space to escape the shots of others. This could lend itself to some nice back and forth and how to strategically use shots to cover enough ground to hit an opponent. Think.. putting in golf games where you need to take in the level of the grass into account... just in 3D... around planets. Kinda cool and satisfying zipping shots around planets to hit targets, but unfortunately not much content yet. Another problem are some control issues, sometimes my ship is randomly exploding when I shoot and I cant figure out why. With some more polish and content, this could be a good game.
