Really interesting game. At the beginning I thought that game would be very simple, you need to change scale that's all, but the game gets more and more complex! I love it!!! I managed to play all your levels and the last levels are really challenging. However I have few comments regarding gameplay.
1. The game should clearly inform player that some of axis aren't available for the player. It is really confusing sometimes when you need to check it manually 😃
2. The chain mechanics it is a little bit confusing since if we have three objects lets say: A,B,C and we link together A and B and then we link together : B and C and then we change scale on C, the A don't change its scale though it's is linked with B so if B changes scale so should A. I hope you understand me 😊
In conclusion, I had a great time playing your game and I'm looking forward to the next levels!
