I enjoyed the artwork and soundtrack!
I think it could be cool if there was some soft ambient noises based off the artwork near the ink/player. So if the art was a birdlike thing, maybe you hear some soft bird noises
I fell off the right side and it kept going and when i hit escape it didnt bring up a menu but instead simply exited the game.
lastly i enjoyed the freedom to roam but couldnt find out what the goal/objective was so I couldnt win/beat/finish the game.
