Thank you! I agree, it could be faster, maybe increasing walking speed or adding a sprint feature would work.
The fact that you cannot destroy clones was an intended game mechanic and I originally intended to have a rewind feature to allow you to undo clones. However, my thinking was that it was part of the challenge. I appreciate your feedback though and will try to think of ways to make this more enjoyable, maybe with a rewind feature or undo button.
Thanks for playing and rating!
