This game is absolutely adorable, and I love nearly everything about it. The main issues were that you were occasionally unable to jump if moving (important to be able to jump and move otherwise time is wasted, which is bad on a game with a time limit). I also found that if you were close to the side of a block you would be unable to make it to the top without moving back and forth. Another thing that was frustrating was the clinging to the wall. If there was a feature to wall jump, like tiger climbing gear in terraria, then this would've been fine, but because there is no wall jump it just proved to be a nuisance as it prevented you from falling quickly (again, wasting time). I thought the animation for Laika (cute reference to that poor dog) clinging to the side was so cute though.
