Yeah, I really missed the mark on the ore, I was going for a "vein of gold" feel but since I didn't really texture the ground, I didn't have a sensible way to make the mound so just did the a crummy "decal". I actually wanted to have blast off scene at the end but having submitted with only 21 seconds to spare, it also got cut.
For the blue obstacles, I'm assuming it's these doors, you should be able able to hold shift to boost through them and if they close, you should be able to back up just enough till they open, make sure your boost has recharged to get through quickly. I debated, and still might, make it a dash. Thinking about it, I'm guess you were backing up but then when turning back around to face the right direction and would end up triggering it closed again? For other reasons I was looking over the movement code and the robot facing direction doesn't matter so can boost in the opposite direction still at full speed.
Thanks again for playing and the feedback!
