I really like the artstyle, especially the UI looks really good, and I think with some sound effects and music this could really have a great atmosphere but I found some bugs that break the game for me, and I really like the idea of the battery that runs out for the time mechanic.
Unfortunately after opening the first chest the next showed just this empty textbox, and when opening the one in the first room to the top the game froze, tried again and it froze even the second time.

This happened in another room, the one after the hallway, all the way to the top, and also all the battery drops except the first one won't be picked up by the player.
I also found that I could not go to the rooms all the way to the right, maybe I'm missing something.

Tried the game out,  like the below I summoned a giant collider, but I found I could swing it around by clicking in other directions so I got it out of my way and wandered around for a while. Then my light ran out and my health ran out and I hit the end game. Overall I like your tileset and the idea of a light based survival system is super fun. I also love big weapons. Seems like the project might not have gotten fully completed.

So I tried the game.

There was no audio. Is that intended?

It is not clear what you have to do and there are no instructions.

When I right click a yellow bar appears and it also has a hitbox.

This means i cannot walk with my character.

There is also no way to remove that.

I like the atmosphere you are going for but I wasn't really playable :)
