Very cool game! I enjoyed being able to shoot fireworks at the props. The double jump and dash are very welcome additions that give the player more control over the dog. The graphics are solid and clearly show what's happening on screen. The music kicks ass and fits the destructive mechanics of the game. The sound effect that plays when a prop is destroying gives very satisfying feedback to the player.
However, I did manage to complete the game without using the shadow mechanic. I wish that the dog's collision collider didn't have rounded edges so that the dog wouldn't slip off the edges of platforms. Also, the dog is very slippery XD
Overall, I had fun playing this game! Well done!
