Thank you so much for the detailed feedback! I completely agree with your points.
I actually tested the game on mobile yesterday and realized that the energy bar would work much better above the object the player is currently spinning around. On mobile, having it next to the cursor means it gets covered by your finger.
For the right mouse button, I’m planning to add an alternative input, such as the Space key, and probably also a UI button for mobile.
Releasing the left mouse button currently slows down the rotation, so I would probably keep that behavior as it is.
I also agree that Level 1 would work much better as an in-game tutorial, where the goal and controls are introduced gradually during play. 😄
I’m also thinking about adding a simple story and more varied environments in the future.
Thanks again for the feedback! I’ll definitely work these changes into a future update.
