Such a cool intro and premise, really well put together! I really liked the opening cutscene.
A few small notes: the wall climb/lean seemed to kick in a bit too quickly at times when I wasn’t expecting it, and maybe consider adding a bit of coyote time (or a bit more if it’s already there) for jumping. Also, a small nit-pick, I wasn’t a big fan of how the dust particles looked.
Overall, great job!
As for expanding on it, this could make for a really cool little roguelite. Definitely worth giving it some more thought!
