I really enjoyed the little touch of the pink square character flattening and rising when landing from a jump. It added personality however the need to wait for the animation to finish before jumping again interrupted the flow. It would feel much smoother if you could jump instantly. The variable jump heights was a nice feature, but in this game I think it would have worked better if the jumps were always set at the maximum height to make it easier to jump over the dog enemies, I know that would remove the challenge but I believe controls should always help the player to do what they want to do.

Visually the game is stunning, the backgrounds and overall art style are fantastic. I especially loved the dogs - they looked so cool and fit the world nicely but I did notice the dogs are not quite on the same ground level as the pink square character. I'm not sure if that was intentional or just a mistake. But they sometimes started a little too close for my liking when I started a new level. I wanted to keep moving forward but I couldn't do that without bumping into one. These are small things but I think they could make a big difference. 

I like that once you collect the stars you can't go back and are in the new dimension. Talking to the different ghosts and getting a new item in your inventory was nice, I just didn't know what I was supposed to do with my items  to finish the game, I'm guessing you have to talk to the correct ghost when you get a certain item, and do a lot of going back and forth. Overall a good entry, well done.
