Ahh crap you are right, its because i tested on an 2560x1080 screen, i cannot update it until the rating is over, so if you would like try to play at 2560x1080. Also thanks to the report. :)
You can change the UI Scale Mode to Scale With Screen Size at the Canvas Scaler in the Canvas!
yes, i know but i can't upload the new version of the game until the rating period is over :(
