Short and simple platformer with combat. I liked it, and you’ve listed most of the issues I ran into as things that are fixed for a later version, so no need to bring those up.
I felt the jumping was a little bit unpredictable and I struggled a few times to grab rubies I though I for sure was touching. The movement was a bit floaty, I’d really recommend looking at some of the “game feel” videos or essays about platformer movement specifically, there are a lot of small things that would make it feel great!
Good job on the game, it was fun!
