I fixed the problem. If you didn't try all three of your save slots, the ones you didn't play should work fine in v0.0.101. If you have a backup, it should now restore properly. **EDIT** Email games@hexsw.com if you want your approximate progress restored.
Hard Badge Guide: Day 1 - Max out Trans+Engine+Tires and spend the rest on fuel. Hold down the Only take your foot off the accelerator if you're going to be off the ground for more than about half a second. Try and keep your wheels parallel to the ground. You should get around $730. Day 2 - Max out fuel, get the autogun and as much ammunition as you can afford. Do the same as before. When you reach the final hill, it's broken into three slopes. You should be able to get part way up the third. If not, restart and try again. Day 3 - Put everything into Boost. Do the same as the previous day, and when you hit the the third slope of the hill, hold boost and fly over the barrels. Don't bother voting up, just repost.
also don't let the snake body block your projectiles :p
