Great feedback on everything, thank you!
I like the idea of cover to make the level more interesting, we'll play with that idea in the future for sure.
As for boss vs player design, that's a very fair point. Our team is newer to making assets so we used a hybrid of our own and purchased assets, so the player was our creation while the first boss was a purchased asset. We'll definitely be honing our skills as we continue making games though :)
Thank you for taking the time to rate and give input, good luck in the jam!
