How do I unlock these?

When I go into battle, the entire 3 bottom rows of the arena are cut off. I can't even see my characters until I move them up a space. If they get knocked back down there it becomes unplayable. All resolutions do this. Is there a way to scroll down or zoom out the arena?...

I was in the middle of an endless run, 50 fights in. First I had one of my gladiators knocked out.. he took 65 physical damage, his armor negated 30 of it, but took 65 total points of damage. His armor did nothing, the math is seriously wrong, 60- (65-30) will never equal -65. Secondly I got an event where one choice was to "supercharge skills".. I tried it out and it randomized the skills. When in what world is supercharge the same as randomize? This ruined my run, I almost uninstalled the game. This fee...

For some reason I'm not earning any Steam achievements.
