Good game. There seems to be an issue in the Upgrades section though. When I try to add any points to Speed Boost or Triple Shot instead of increasing the number/bar, the amount of points goes into the negative, like it's counting down from zero for every point I put into it. Then if I come back to the screen again and click a point in, it'll reset back to zero. Then if I try and put points in again, it starts counting into the negative again. Could this be fixed by any chance? I love the game but that is really annoying since I lost like 12k points the first time I went to the Upgrade area because of this. Thanks.
