The enemies don't hit you from far away, I've even just tested it. But with the controls thing, I actually forgot to post the controls on the page, ngl. I was rushing to get the game posted onto the page, so I just forgot to paste the controls. But thanks for the feedback.
After the GameJam is over, im planning on this being an actual RPG with an overarching story, so the whole "level progression" idea isn't gonna be plausible.
I just watched, and fun fact, it's my first released game. I am working on other games as well, like, for example, a 3D first person platforming game that I'm developing right now in Unity
Don't worry, the full game will be easier for World 1. I just wanted some progression for the demo so people didn't think it was too easy. But if you want to help, make sure to donate! <3
