The idea behind this is awesome, and you guys have managed a great deal of polish and atmosphere. Art style is fantastic and sound effects all work very well. its really fun to step into someone's bubble and see the text pop up and here them talk!
I think I found it really hard to keep all my targets in mind. If there had been more time, I think a simpler tutorial level would have been great, with slower moving targets and less going on. A way to review targets again though, most importantly, would have kept me a lot more engaged I think, as without that I had to kind of just resign myself to losing when I'd noticed I'd forgotten.
