As well as being a song by Pink Floyd. Echoes is a totally cool freeware 2D shooter. Yesterday I posted that I was thinking about doing a 2D shooter for my project after Caverns, and Echoes has the exact control scheme I had in mind - which is good, because now I know it works
The controls are basically an updated version of Robotron which I’ve never actually played. Movement and directional fire are de-coupled from each other. You can either use the mouse for movement and the keys for directional firing or (my favourite) mouse for directional firing and keys for movement.

This game is very, very good. I usually rate 2D shooters by how many curse words come out of my mouth and Echoes gets a score of about 4 cwpm (curse words per minute) - I only wish it had a more relaxed mode, so you can kinda chill out for a bit longer before the difficulty ramps up. I also like the mini-tasks in the game like ‘get 150k points without moving’ and ‘get to level 7 without using any powerups’ which apparently unlock a bonus game. I haven’t got to unlock it yet, but I’m trying!

Lots of things to remember when I come to code my own shooter.
