the "click to pump" thing is honestly something that i wanted to implement in a game for a VERY long time lol (it's basically the reason why there are shotguns - and even reloading in general - in this game). it always seemed to me that it would be really cool to have in a game, and i'm glad you find it good and not annoying ;D
i'm pretty sure that is the only bit of something resembling a story in the game - though i'd like to keep that sort of ominous but kind of irreverent mood going. i think it fits, and i'm happy that you find it engaging :) Cruelty Squad is a major inspiration, yeah - though i don't know if i'll fully take it into the "immersive sim" territory (just for the sake of keeping it lean). however yeah, some more "stealth" options would be cool to have!
also, i really need to finally get round to playing EYE already as people keep comparing this game to it lol
