You are using WASD, right? I have tested both the download and the in-browser versions, and the character can move. Moving, granted, is not very fluid, but I haven't watched any tutorials or nothing, I just made the movement mechanics. I will try to make movement smoother in future projects, and I may even update the game once the jam is over.

You still haven't specified about not being able to move. Wasd and space work perfectly fine on my end. If you are talking about fluid movement, which I assume you are, I appreciate the feedback, but I know that the movement isn't very fluid. I may either try updating the game or try to learn how to make more fluid movement. Yes, I know tutorials exist for people like me to watch. I don't absorb tutorial very well, and I always end up just copying stuff down, while not learning anything about how it works. I want to be able to understand my code.
