Thanks so much for the feedback! Glad you enjoyed it!
Yeah the performance is really bad. I was supposed to make a Potato PC edition, but I ran out of time near the end. I've made one now though, with a few graphical effects turned off and a dynamic resolution, so hopefully that should help somewhat (It runs now on my tablet, at least!). The text runs on a separate co-routine to the script that resets the text and moves the light, so that's why it can mangle itself on low framerates. Oops!
In terms of the relation to ND64, it wasn't really intended, but I ended up going for a similar narrative structure, which kind of explains the similarities.
Anyway, thanks so much for playing and taking the time to review!
