Hello Nilrat,
Thank you for the very much for the very needed feedback. The stability system is a bit broken atm and that is something we're planning on fixing and optimizing with the next builds. That is such a great idea with the semi-transparent match pieces like in tetris and puyo puyo! I can't believe we didn't think of that before. Buy hey, that's what alphas are for, right? We'll make sure to take all your feedback and use it to help develop a more improved build our game that we'll release next week. Once again, thank you for your advice and we hope you enjoy the next builds of our game in the upcoming weeks!
