Love your small experimental games? I sure do and one I came across recently called Island Artist is absolutely wonderful.
It features a hand-crafted world where you walk around and create wonderful paintings. It reminds me quite a lot of Shutter Stroll and gives off that same kind of vibe. There's no depth to the game other than walk around, chill out and perhaps create your next masterpiece, although the tools are simple so don't expect too much from it. Something to help you find that inner peace on a rainy day perhaps?
You can find it on itch.io if it looks like it might be your thing.
