You need to turn that bloom down, it's way too powerful. And it took me some time to realise that I needed to be still, jump on the wall, then press W to wall jump, as opposed to jumping on the wall while moving and holding the W button, personally the latter method should be allowed to make the player feel more animated. I also couldn't see where the theme was being used here. Had fun with the tutorial level but couldn't get very far with the first level. Is that music your own? It sounds very good!
