The art direction is fantastic and perfectly fits the theme. Great work ! I like where you were going with the SFX for footsteps, but I feel like they were not loud enough. There was also some missing for certain actions.
Regarding level design, there were distinct areas. However, it was hard to navigate and understand where I was.
Gameplay wise, the wall run is way too strong and negates most platforming challenges once you get it. I had fun with the movement overall though.
Props on the functioning save system !
Overall, I'd say this is a pretty good entry ! Good job !
