Okay, some things I should mention.
1. The usual fullscreen option didn't exist, and I couldn't capture my cursor into the webapp. This was a bit of a problem for maintaining control throughout gameplay.
2. There was a long black section as an intro. I'm certain that something was supposed to be there, I just didn't see it.
Other than those, it's pretty good! Cat v. Roomba is a time-honored tradition, and we're all here for it.
