Thanks for playing! Glad you liked it :D
The collision for items is only on the pedestal they're on, not the item itself, so you just have to aim a little lower in order to interact with them. It annoys me as well so it's something I'll resolve for the post-jam version.
Ranged enemies are indeed tricky. Crossbowing them from around the corner then ducking back into cover is a viable tactic, and you can also try to lure them towards you that way for the poke. Or, if you have room for it, it's possible to get up close and dodge their projectiles at point blank range if you time it just right. And running away is also a viable strategy :D
