I could see how this game departs from first year's Run Faster. It truly shows the innovative screen splitting and control as a local multiplayer game. The aesthetic is very charming and the contrast between cute theming and all the ferocious action just feels attractive and relaxing.
My only suggestion about this game is, probably not to this game but a future iteration of this genre of game: Make a simple version of it that can already contain so much fun! Try to limit the ability of all the characters to one. For example, the player will only have to push boxes and solve puzzles, while the antagonist will throw some cages and boxes to mess up their plan. That will make the game so much easier to balance and for players to catch up, unlocking a better utilization of the dedicated design map to set up some indirect level design.
