I think it would be nice to have some extra features.
1. The ability to save or export the game state. I had to start a new game after a browser cache cleanup.
2. The ability to turn sounds off. They're maddening after a while, especially if I switch to doing something else while waiting for some in-game task to complete.
I'm enjoying the game, though, it is nice and cozy. Thank you.
I think it would be nice to get half our ammo back when gear upgrade fails in the arsenal. It fails quite often after reaching a certain level and I think it's quite unfair to take all the "money" and give nothing in return.
