I'm glad you liked the concept! Sorry for the frustration :( Unfortunately in-game cursor isn't tied to actual cursor position so even a smallest lag can mess a lot with it's movement. As for the audio, it isn't at all how we wanted it to be. 90% of our sound designer's work didn't actually get implemented into the final build (some bad planning). We will probably upload a fixed version in the future.
Anyway, thanks for playing!
