Hi, played the Windows export, managed to somehow miss the web version, so some of the feedback might be outdated.
I think this is really impressive for your first real game made in a week! Personally, 3D design is well outside my comfort zone, and this felt well put together. Am excited to see where you will take it!
The visuals felt good, simple but easy to read, i always knew what I should be doing and did not feel lost. It also ran smoothly.
The enemies seemed to have a slight glitch happening where if they get attacked during their death animation, they seemingly "came back to life" for a second. Maybe this is fixed in the web version already?
I think this is a great job for your first proper project, with a time limit to boot! Excited to see where it will be going :)
