Welcome to the Pet Rescue Community
Do you need help with your game? Ask the Community for help.
The more you progress in the game, the more challenging the levels will get. This is part of the game design and the fun. All levels are possible to pass without any Boosters even though som of them are super tricky.
I understand that the fun goes missing if the levels feel way to hard and I will pass your feedback to the game studio.
Have you checked the new Pet game btw, Pet Rescue Puzzle?
Switch over to that game for a while if you get stuck in the original Pet Rescue. The game had the same idea, but in a new updated design.
