This is fantastic! Super original, clean aesthetic and I love the feature and encouragement to share any wacky drawings at the end. Seriously nice work! The only thing I can think to suggest is that you it might be worth puting the distance counter on (or closer to) the paintbrush circle - I often found myself looking at the count rather than the brush itself- though I guess that might ruin the aesthetic and might also make for some less wacky drawings (which is half the fun). Honestly a super minor suggestion though - seriously nice work!
PS. Here's my whale. Looks a bit like he has ears!
