Love how the movement feels, the wall jump especially is satisfying and easy to get used to.
The difficulty ramps up quickly, but it works fine because you have more freedom in how to navigate the level, which is great. After my first completion I found out how you implemented the theme, and suddenly a lot of the level parts / obstacles make sense in why they allowed you to take the easy way.
I'm not super great at platformers and since there are no checkpoints I didn't get super far, but I like how the level design was done.
Though some parts of the background blended in a bit with the level itself, so sometimes I wasn't sure where the wall stopped, and in some spots the spikes could have a bit more contrast from the level/background.
