Hello! So sorry you had this problem. Here are a few things to try:
1) Sometimes the bee gets stuck on small corners that are hard to see. If this happens, press a few different directions.
2) If you are traveling the perimeter of an existing shape - you can hold 2 directions at once. For example, if you are going down and about to turn right, hold down + right at the same time to immediately turn right once you reach that corner.
However, this may not be the problem you are experiencing! So, do you mind telling us what operating system and web browser you are using?
We hope that you were still able to enjoy some of the art in the game anyway ;v; <3
