Hello! Welcome to Feedback Quest 5! It's nice to meet you! My name's Hythrain. I'm part of the FQ team and a hobbystreamer. I'm writing this review live after having played your game.
Since this is a prototype, I can't rate artwork and sound for this. However, I may cover these in feedback.
Gameplay felt smooth and the controls made sense to me after a touch of trial and error. I don't remember if wall jumping was explained to the player. I don't think it was, and it was honestly luck that I figured it out. It was a bit weird to use dashing to kill enemies, but that's a me thing. Overall, I like where it's starting.
What you should do next is make a bigger screen and zoom the player in more. Everything is incredibly tiny and your character can blend in with the stage. Making them bigger can let you add details to make them stand out more, and in generally it'll be better for the player. Also, some sounds for specific player inputs so that they can use it to verify the input they wanted if they're, perhaps, in a position to not know if they're dashing or wall jumping when they want to be.
