Nice game :) It was a little challanging for me but totally doable and really fun.
The animation of the players when you finish a level is really cute. Maybe you could add some more levels and different other mechanics to the game in the future, I would like to play a longer version of this. Maybe something like moving platforms, enemies that are active when a button is pressed or projectile shooting cannons, etc...
(P.s. I would appreciate it if you could try out my game)
I died a lot of time but it was still very enjoyable.
Keep up the good work :)
