Cool game, I liked it, but a couple things bugged me: the inability of my off-road truck to crush an apple or bottle under its tires, and the final vehicle upgrade was incredibly lame. I was hoping for more spikes or crushing power or anything useful at all.
This is a solid foundation for a game, it plays well and it looks great! I hope that you'll continue with this project. I was disappointed when the difficulty slumped after the (admittedly really cool) platforming level.
Strat for the 1k hatchback challenge: 1) Buy the best tires, trans, engine, and spend the rest on fuel. Get to 700 ft. 2) Spend rest on fuel, spend rest on gun and ammo. This should get you up to the final ledge. 3) Buy all but the last 2-3 ammo, and the rest on boost. Don't gas in the air, tap back over large rocks, keep your wheels down to keep your speed up. Boost up the last hill and over/through the boxes FTW
