It took me nearly half an hour, but I got all the toodles and stars!
Oh.
In seriousness though, I really, really like this game, and the simplistic artstyle matched the flowstate it put me in. I would highly recommend turtle save points though, and have dead/lost turtles go to the nearest one instead of all the way back to their spawns. It was pretty frustrating having to slowly make my way throughout the whole map recollecting turtles, especially when I died and had to recollect all of them. I'd also recommend making the spikes stand out more, especially the singular ones. Some up against walls looked more like slopes than spikes
