Its a fun idea, but the execution was lacking...
I like puzzle games, and this one is up my ally...its just too hard and unpredictable. I played it for a good 10 minutes and I still couldnt get it just right.
Sometimes it crashed.
They way you used the theme of the jam was a bit of a strech, something I've seen a bunch so far, but I liked the art style, its a fun scribly art styel and Im all in for it.
Overall, its sadly a 1.5/5, its just not engaging in any way,
But dont let that discourage you! In fact, the opposite! Try and do better next time, you seem to be very clever with this type of mechanics. Maybe take your time and experiment with this idea, and who know?, you might just create a new mobile game that will strike you a jackpot!
