How to get the hard badge: First you - upgrade engines, wheels and fuel to the max; get transmissions for 200$, and buy boost and fill it. Day 2 - upgrade transmissions and boost to max (if you can upgrade the weapon). Day 3 - upgrade weapon as far as you can, pass the last 2 steep hills and after them there is a gentle hill (there use all of your boost + fuel), so you can fly above all boxes :) Hope it helps !
A well - made game indeed, but I found it quite imbalanced. Firstly companions are useless and I never learned how to revive them... As I started playing it was quite interesting, later on gets repetitive. And finally I got a weird bug - had a NaN/160 limit bag which is unlimited, so i stored everything lol. 4/5
How about TheFinalChapters add red colored bullets (another color than white will do it) to bosses? (so everyone can see which bullets are which) thumbs up who like the idea, so TheFinalChapters can do it in this game, or in their next one.
