This was an interesting concept. I was hoping for something similar to the game we've created, but it took a twist!
It took me a few goes to realise what I had to do, which wasn't helped by the game window not being able to go full screen, which meant I couldn't see what the asdf keys did. I also took a moment (and another death) to realise that you had to hover over enemies with the mouse.
I think the pacing of the enemies could do with some work. I felt swamped from the start, and died after the second type of enemies turned up.
I also think I spent longer reading dialogue over a black screen than I did actually playing the game. The intro and world building were good and interesting, but didn't explain anything about the game to come so my attention was already somewhat spent before starting the 'game' part.
