Going into these jams I value uniqueness and an enjoyable experience over things like visuals or polish, so I'm absolutely thrilled that you got that from playing the game. I try to nail the gameplay aspect first before working on the visuals, so only the bike and cars got any modeling attention. Those cubic buildings are next in line for a revamp though! I love your idea for more natural road patterns. A grid was simplest to implement, but having curves and different intersection types would give the map much more personality. Accidents and blocked paths sound like a perfect way to throw off a player's plan and keep them on their toes. Thanks for your feedback!
