Thanks for commenting!
Sorry about the "Run" key, made it rebind-able and defaulting to both left and right shift in latest version.
Good point about the items, too. As it is, most items are random. In some later missions, there are locked rooms full of sentry-guns and body armor, that spawn every time. I do like the randomization, as it requires more careful thinking about what to take on a mission, but you've made me realize I should make the randomized item spawn dependent upon what's already in the player's inventory.
Others have mentioned the C4 too, so it could probably do with a nerf.
Thanks again for playing and taking the time to comment, It really helps!
