Wow, thank you for trying so many times! Yeah it really sucks that the page moves when using arrow keys, and that I forgot to map the WASD keys to movement.
The only way around that now is to play in fullscreen unfortunately.
The ropes can indeed be climbed with the up arrow. If you're willing to try again (and I completely understand if you're not) try clicking on the game (bringing focus to it essentially ). The itch.io page will probably still move, but at least you should have full controls in the game. Or try fullscreen.
Yeah the slow running was a design choice. I understood that not everyone will like that, but I wanted it to feel like you're in one of those dream/nightmare where you move in almost slow motion; but too slow would be boring, and too fast would feel generic IMO. It's supposed to feel awkward though.
Anyways, thanks again for playing, Cheers!
