What if the character's body could be ripped apart, just as the vehicle parts could? I think you could just enable it for certain levels/in the options screen, and thus this would create a sense of "health" for the character... I dunno. I feel like it could get annoying, so I think it should be toggle-able, should you decide to implement it.

Hey Mark! I've been playing your game for ages now, and I love it. In fact, I bought it 14 minutes after you posted about it's release. :P

I have one problem, though. The delete button doesn't seem to do anything! I'm unable to Save As/Over my saved vehicles aswell as delete them. Please fix the save system if you can, because It's driving me insane. >:(

Maybe I have OCB?

I find levels with turns (especially 22) much more difficult than they should be because I'm constantly having to move the camera around. I also tried to make a loop-the-loop in the level editor but am rarely able to complete it because I can't see for half of it.

It would be great if there was a "chase camera", i.e. a camera facing the rear of the vehicle fixed to the forward direction of the vehicle, as found in most racing games.

A camera fixed to some part of the vehicle would be nice too (like a bonnet/hood cam in racing games) - maybe this could be implemented with a camera item that could be attached to the vehicle? A first-person robot cam wouldn't be so useful as his head tends to move around a lot, but could be interesting for replays.

Would a Android or iOS version be possible?

My gaming rig is far too huge for me to take on trips and such.
I would love to take this game with me everywhere I go.

 We can already kinda make planes, but there aren't really any challenges requiring the taking off and clean landing of planes... Boat physics would be tougher, especially with water physics integration, but I'm sure you could boil it down to little more than dampening buffers... I think it'd be worth it, though

Ropes... Catapults.... Fun :D
