Mechanics feel great for the most part, except sprint is kind of too subtle, and jumping off walls is tricky because the guy falls if press the opposite-to-wall horizontal arrow key - so you can only jump up.
Thanks for the feedback! Sprinting was kinda just an after thought. Wall jumping was a bit tricky to implement, I really wanted to make the player able to get “launched” off the wall when jumping like in other traditional platformers but I sadly wasn’t really able to code that.
