could you add character specific upgrades instead of only weapon pick up like a store that you had to fight to this would be better with like a map and location you can go to. Also a surival mode would be cool 5/5 game definetly waiting for the 2nd
if going for for the 3 minute achievement only worry about yourself collect the other people but mainly just stay ALIVE i got the 3 minute and points one without trying ot do anything but live
to space line you said the max score is 10000 i got 9117 without actually trying you said doing each lv in a nanosecond would get 10000 well your making stuff up
