Thank you for playing and for the feedback 👍🏻
Yes, I should have added a hint in the beginning. It was planned but eventually cut along with other improvements due to time constraints.
I want to add more levels in the next version. I have some cool ideas 😎
I think it's cool that the player has to walk slowly and use echo often. But I will try to play a little bit with echo speed and max distance. These mechanics and levels take a lot of time to play-test and fine-tune 😇
