I suggest a buyable freezer or fridge where you can store a certain amount of fish or burger..maybe start with a small one (lvl 10 req. and storage capacity 20) and let us buy every 10 or 20 levels a new one (maybe a "black hole" fridge with infinite capacity)
needs some kind of an upgrade system for each car...
it should be harder to get a new car...got the best after 3 races...the comp driver are not very good...guess its possible to win each track with the custom car...
I loved that game! Challenging and the game rewards thinking more than brute force...Upgrading Pilots, own Settings for each mission with different planes and weapons---> Game of the Year.
