I'll start by saying I love the aesthetic and by extension the theme interpretation.
Now, everyone's told you about the movement already and I sort of don't want to just copy and paste what the others said. Slow paced games are not my cup of tea and I'm aware of it, HOWEVER I think I can cheer for what you have going on here with adjustments. The jump actually doesn't feel that bad, at some point you get used to the distance it covers horizontally and vertically and it gets easier to properly time them. But wow, starting all the way back when making a single mistake is a killer. The "floatiness", especially towards the end of the jump, can ruin your whole movement. Overall I like the idea, but the execution needs more polish.
With this movement speed I'd cheer for a sheep clad in armor.
