This is really funny concept, and even the title is chuckle-inducing. Pretty much charmed from start to finish, didn't notice any bugs, and couldn't believe how much polish you'd squeezed into the UI.
I only did one run, but things seemed pretty balanced and engaging enough. I suppose being completely random (which I'm only making an assumption about) may potentially facilitate some odd difficulty swings, but the runs are short enough that it doesn't seem like it'd cause much issue.
My only criticism – and it's a small one – but I kind of wish the tutorial was a little more hands on. It for sure taught me the mechanics, I was just eager to try things out for myself while going through it.
Overall, really impressive stuff!
