I like how many games out there are using shooting as a non-violent mechanic. While there were traces of it around before Portal, that was really the game that started the movement. First person puzzle games have really taken off. While it may not be super new, Red Trigger is a simple free to play puzzle shooter which aims to impress with simple and highly contrasting settings and colours.
The gun you carry in Red Trigger is essentially a portable button battery. You are able to use it to remotely interact with red platforms to move them in or out. You can interact with three platforms at the same time before the charges expire. using these you then must navigate your way though a range of logic and dexterity focused challenges. Pictured above is a puzzle where you have to use the red blocks to obscure the dangerous red beams of death.
As these blocks move in and out they carry a momentum, something which you can use to your own benefit. They will fling you higher or flick you across the map; all you need to do is time your jumps and your shots correctly. On the whole it is quite satisfying, it is therefor unfortunate when you encounter bugs and skips. There were a couple of times where I accidentally did something which made my character behave in an erratic fashion. This was something that, in more than one case, enabled me to skip small chunks of puzzles.
There is a story to this game, but I cannot for the life of me remember what it is or what the final outcome was (I am fairly sure that “you won!”) However, given the length, of the game this does not disappoint me. It is a title which is clearly exploring the use of a single mechanic; the story is there purely to explore different combinations of this power.
