Good game concept. I managed to finish it. The control was good, but I think if you try to circle around the main mechanic and add more level components, it will definitely make the game even more fun.
The game is so relaxing, and if that was the intention behind it's design, then it's total success! There is almost no sense of urgency or intensity. However, it's lacking juice, you need to add lot of juicy effect for better player experience.
I'm sure your only problem was maybe due time, it takes time to get an idea for the game jam, not to mention developing it especially if you try new ideas , great job.
