Roboquest.
Fast paced fps rogue-lite. Its got a bit of story, though it basically boils down to 'punch bots'.

There are 'classes', but it's really just whatever special ability you want. And there are stats on guns, but those can mostly be ignored as you can just upgrade whatever weapon you have or like to use.
Also, nunchuck cast iron pans.
