Thanks for playing and for your comments.
I agree about the difficulty for jams. I noticed that the levels were on the easy side but it didn't seem people could just breeze though levels, so I felt the difficulty was alright.
I intend to improve on the direction indication. I wasn't super happy with it in the end but I ran out of time.
I also feel I need one extra dialog when the black hole is first introduced. It takes a while to figure out how to use it to clear levels.
Again thanks for your comments.
