Your game have potential
This is what i can see you could improve :
- The song : It start to hurt my ears early and you could improve it
- The controls : find a way to disable diagonal movement because sometimes i fail a push and it move diagonaly
- a small bug that could mess up with your puzzles : you can disable two add in one level in the bigger case for them
Try to improve that and tweak the way we push the block ( because it feel out of our control sometimes ) and it will be better . Good luck for your next game
