I'm loving Lost London thus far. There's a lot of awesome there.
The tempest rifle feels weird, though. It feels like a weapon beta testers would use to rush through the game effortlessly that was left in accidentally, or that was changed to test something and never got changed back. It's just ridiculously powerful with the higher firing rate, especially with the larger sizes of bosses. Running down corridors with it blasting away feels like pushing a giant electric plow in front of me that annihilates everything it hits.
There's another topic here about changing the firing rate, so I'm going to do that for my own game, but I figured I'd mention it here as well.
