since this game is all about the editing tool, I think it could benefit from some improved usability. While I'm sure I'm suffering for playing on my laptop (my motherboard is fried), it's awkward doing work at the edges of the screen. Lots of potential fun though.
All 4 arrows are not a fantastic interface for this game, maybe that's just me but given the orientation to the map I'd rather have gas and break in a different hand from turning.
