press space when you are near the microscope
its in the first room the microscope
And to control cat wasd + click to shoot
I see now. Would be nice if there was something letting you know that it could be interacted with and instructions on what key to press (at least included in the description of the game). I thought that it might've been interactable but I was pressing keys like E and F and it wasn't working so I moved on. Just some clarity would've been helpful. In that regard, ignore what I said and besides the clarity issues, great work on the game. :P
