Thank you so much! When we see long reviews, we’re sometimes afraid to read them, but this one was especially nice because you noticed the little details that actually take us a lot of time to develop. We’re really glad you noticed them! Thank you!
Sound effects and teleportation when falling into an abyss (to avoid having to restart the level due to a mistake) were added in version 0.9.9, which is currently available only on Patreon. DevLog: https://yjproject.itch.io/nly/devlog/1618382/nly-099-patreon
Tutorials, along with many other features, will be added in upcoming updates. We understand that this is an important part of the game that will make it easier to understand the game mechanics.
