It took just over an hour, but eventually drifting_viper snuffled out what I feel like has been one of the more technically accurate scribbles of mine since I started at Kotaku. It was Sonic Spinball, specifically one of the windsocks on the Robotnik boss battle stage. Nice job.
Let's move onto today's game, shall we?
Good luck! And if you want to play along, send your drawings in!
