Hello everyone,
I've put an update for the Achievements, it seems to work for some user and not for the other, and the pop-up windows that announce the achievement is not displayed properly (only when you close the game), I'll try to fix those issues as soon as possible, sorry for the inconvenience, and thank you for your patience.
Also, I solved a bug where you were able to pass through the blue-circle obstacle.
Thank you for your support.
