Thanks a lot for playing.
Yup, the "level design" I found in the end to be very lack-luster. The violin was supposed to be a funny joke, but also a gameplay element, but the levels weren't designed around it really. So it just gets discarded every time, since it's so bulky.
The readability is another issue, true. Those white borders were not enough to indicate shapes when everything is so busy and crowded.
Thank you for the feedback :)
