First thing that stood out is that there is only a Windows download. GWJ requires your submissions be playable on Windows, macOS, and Linux, either with downloads for each, or a web export. We are on Linux, so I had to play this with Wine. It did start up and seemed to play fine.
It would be nice if there were some instructions, especially the controls, even if just on the game page. I found WASD worked for movement, with left mouse to use the currently selected item, E when it comes up to interact with furniture, and 1-3 to select a slot. I'm not sure if I missed any others, especially any that may only activate under certain circumstances. It started in full screen, and I tried to switch out of it, though none of the key combos I tried worked.
The gameplay worked decent, though it was certainly on the harder side, especially depending on what your random unlimited item was. The enemies firing things that fly through the walls to hit you, and have a fairly long life, being in the first room, felt like a bit much. I'd tone down the early enemies to give the player time to learn the controls and get used to it, even if you just give a few rooms before crazy big projectiles flying all over the place and limited space for you to evade them.
I found that the first room randomly selected 2 pieces of furniture to be interactable. If it was a shelf, I would get an item. If it was a desk I would get the same sound as a chest, but no item popped up.
The bright white flash when getting an item is way too bright. It was very unpleasant, and limited how long I played. In a dim room it would be even worse, and there are people with health issues that it could be very problematic for. If you keep it in, you should add a warning about bright flashing lights.
The graphics and audio were good. The base gameplay works well. This has plenty of potential.
