Hello, we're Jipang2Games. Thank you for playing the game and giving me feedback. Through the videos and evaluations you uploaded, we found and improved bugs and optimization. First of all, I modified the bug that occurs in chapter 3. We modified bugs that sometimes do not pick up stones or cause logic progress. There are other optimizations and improvements regarding the light used in the production. In the next update, we will improve the control of picking up stones and the problems related to jumping. Also, we are looking for problems with the part where the game is not played in the low frame and the phenomenon of bouncing while playing the game. Thank you so much for your interest in TurnTack and your feedback. Thank you.
