Yeah, I'm also having an issue getting through the door. I'm at the starting tutorial - I've gotten the sword, killed all the enemies and have tried to walk through the doors but I'm not progressing? Not sure what else I'm suppose to do.
If you pressed R you have to restar the web with F5 (we know a bug that makes the R reset key to block all doors, making it impossible to progress) so if you died or something weird happens always press F5 not R to restart. On gameplay you should kill all enemies before getting access to the doors, but you already did that so the solution should be the first mentioned. Feel free to dm me here I can help you through discord too if you want.
