Thanks for the feedback; we're glad you enjoyed the game! I’d like to add an indicator showing exactly which table to approach at different stages—I might add that in the future, but I just couldn't quite get it polished in time for this release.
As for that cutscene—yes, there is indeed a frame that lingers on a blank screen until you press Z. It serves as a sort of separator between the final shot of the cutscene and the "thank you for playing" message.
