I really enjoyed the start! I liked that the main character is older (not a teenager), and her introduction to the other world was a little more unique as well. I liked her powers as well, with the video game like system. This has been done before, but I feel like I've seen it more from male main characters than female, so that was a little refreshing. The lead herself is fairly likable, but frankly doesn't have that much of a personality or development over time. There are some likable side characters, but they (mostly) don't have development either. (I think one of the side charactersgrows a bit).
The plot was alright, but I didn't love the direction the final arc took.
The art was nice, nothing special, but definitely nice to look at.
I think I would do a reread at some point so I can make a more thorough review.
