Thank you for playing and for your kind comments as well! Glad you enjoy the game!
The time manipulation mechanic is very important to the game, and it's essential that we make that experience as smooth as possible, so making the controls obvious is one of our priorities. Resetting the whole puzzle is also a very good suggestion, this should be a great QoL improvement too. And thank you for that bug you found, we will look into it further. Thank you very much!
