It's really neat! Though the pixel text on is sometimes hard to read or confusing. It's really low-res on the big text dump, making reading it hard, while on the upgrade screen the weight part down below makes the l in lb look like a 1.
The text is a bit big in general, though I do play it in fullscreen on a 2560x1440, so there is that.
On another note, walking requires pressing the button over and over, instead of being able to just hold it down, that's a bit annoying over a long time.
What would also be nice is a way to spend a turn without moving, like walking against a wall. That could with the fights a bit.
