This is impressive work for just one person and the level design is definitely outstanding.
However, as there is a lot of re-use assets, I found myself coming back to the same spot on the map without being really aware of it. That could be easily fixed by adding some small decoration items here and there, that could help players identify their space around tho.
Overall, the game feels really alive and the thumbnail caught my eyes straight away... clearly, you got something powerful between your hands if you want to give it some extra time after the jam!
