I actually like a lot of the effects, like the scroll to show what world you're in currently. I also thought the hex code thing was inventive.
The modelling of the warp device is pretty cool. Also pretty cool to incorporate into a ren'py game. I actually like the warp mechanic too as it seems like one of those infinite easter egg-y VN things that you could have a lot of fun with, and break some of more 'mundane' renpy patterns with.I enjoyed the characterization mostly although you might fall into some character tropes here and there. I liked the plot itself, its definitely got a twilight zone sheen to it. I'm not sure I enjoy the five misery endings. The writing is optimistic that there are mysteries to be resolved and ways to reverse the mistake but you just end up screwed in every dimension. (I realize this might have been a consequence of deadlines)
Congrats on the release!
