Hmm, that could have been the problem. I tried the direction keys on their own, and I think I tried Ctrl too, but didn't think to try multiple keys at once. I would definitely suggest making it only the direction keys, as that feels far more intuitive.
But, yeah, I did definitely try Escape to pause, and that didn't work. Unfortunately, I don't have any controllers. I know a lot of games use P to pause; do you think that would make a difference? (I don't think it should, but you never know.)
Thanks for your reply!
Edit: I just played again, and the dodge does work, but it is very finnicky to have to press both buttons together. Sadly, Escape definitely doesn't work to pause.
