I always love metroidvanias. The wall jumping was neat for a starting ability. The jumping its self felt a bit "floaty"; your character doesn't fall very fast but they do move very fast side-to-side. I didn't know I couldn't wall jump on the side walls and fell all the way down to a previous checkpoint which made me have to redo that whole section again. Also, long dialogue isn't very fun. I much prefer short and to the point dialogue and to hide the tutorial behind a bunch of speech from characters I'm not particularly invested in, is a bit annoying.
Overall though, you made a nice game. I saw it was your second ever so good job.
