Thank you for your feedback :-)
Yeah, at the end there was not enough time for including the in-game tutorial, unfortunately.
eHoodie already improves a copy of the game - as soon as the rating period is over, we will flip the switch. This version has the in-game tutorial and I have also the "shorten the water sound FX" on my list ;-) We also completed the UI (it came out pretty nicely), fixed bugs and added a ton of improvements.
