Very enjoyable music that I felt fit the games aesthetics quite nicely. Loved the art style too. Great looking game I enjoyed playing all the levels. Now for a couple suggestions.
With how difficult it is to maneuver around obstacles, I'd suggest having a larger / taller screen resolution to give the player more vision ahead of them. I also feel like there are some improvements that can be made to the controls. The way I see it there are two options.
- Allow holding of a button to continue stroking.
- If you are looking for precise button presses and feel like holding down a button removes part of the challenge, I'd suggest adding a small input buffer to trigger a stroke. That way if you mistime your click/press you will still do the desired action at the earliest possible moment.
