I had fun :) and the only comments I have I think have been covered in the previous comments haha.. For me I think the gravity is too weak and the bullet is a little fast.. and some times when I mess a puzzle up I know I'm gonna lose anyway so if there was a reset button that would make it easier to restart!
Thanks for the great game! I can see it becoming a full length game build on this mechanic alone! 😄 Good luck!
