You did a phenomenal job with the game design! The levels were well constructed, the graphics worked well with the music and to top it off, it had an interesting story about squirrels. I also liked how you added acorns in every map to challenge the player.
Unfortunately, there's one big issue I had: the controls. Judging this as an RPG Maker game, it's neat but as a platformer game, it's terrible. There were certain parts in the game where I had to jump onto the platform, and it bounced me right back because it collided with the wall. You should seriously consider programming a platformer framework with pixel based movement.
