Level up giftboxes were my only way to get repair powders/nates. /: Also to get sprints and boosters from the other gift boxes. I know I should have thought this much earlier than now but I have absolutely no hope that this game will improve in any way. It just keeps snowballing downhill and once it's reached the bottom it's going to be too heavy to carry back up.
Swallow your pride, because silence is golden, and I wouldn't pay a penny to hear your thoughts.
