A little something that was supposed to go as an ememy to the Crab Tank. Its basically a powerful rifle firing at you from off-screen, but this can be used for various things, such as being used for an FPS if you're ever interested in making those.
On the lower-left corner of the crosshair is an indicator showing how many shots the gun has before it has to reload. The upper-right corner shows a simple metric-scale for aiming. The white circle thing that goes off in the center is the actual shot. I wanted to include the gun's reloading animation in this but I couldn't because iaza limits the frames to 50. This gif uses 48 frames, making it technically the most complicated animation I've put on here so far. | 
True, but I wanted to give the crosshair a bit of a more retro-monochrome look, like the average typical thing. The red can be hard to see against a grey background, but I wanted to give it some authenticity.
Anyways thanks for the compliment :)
