If you press tab enough times in the middle of enemies moving you'll eventually find a hidden "show grid" button. Press space to show the grid (it has to be during enemy movement otherwise you'll just end your own turn). Also if your merchant skill is maxed (~93%) you can sell bulk ammo or stimpacks for more money than you bought them for
I rocketed into into one of the acid lakes on the bottom of the level, and I fell through without dying. So now I got stuck below the floor and I can't die, so I'm stuck :(
It took me 5 tries to beat level 14 on my rogue. Then I finally beat it and get the "carried over" glitch where the town screen freezes and it doesn't save :(
