Very appropriate visuals and sound. Also educational aspect is bonus for me. You must change starting camera so I do not stare at wall and do not know where to go. Also in itch description is not mentioned that you should use mouse, because just with WASD do not change camera. Make mouse sensitivity changeable in settings (for me it was very fast moving). Also contrast bacteria so it is easier to follow where it is. If you continue this, I suggest to use Pokedex approach (I was interested what are those green things). If you will fix these bugs, then I see great educational value in this.
