I had everything prepared to be able to upgrade max speed, acceleration, deceleration, static collection speed (for the resource), collection reach, max HP, defense, and static tank (for the resource), but the last day rush hit that part of the game hard. Definitely something I would approach if I polish it further, the code is mostly there already.
I just feel that I need to add something else to look out for to make the trip for more static something fun to do and not just menial work for the upgrades, I need to think about this a bit, thanks for the feedback!
