Nice looking game with an enjoyable music that really gives the vibe of a 8bit gameboy cartridge. The story is simple but challenging in the way you have to pass each level because controls are not always easy to understand. They feel a bit rigid but probably because I am not used to WASD controls, I prefer arrows.
If I have to suggest something to make it more fluid as experience I would toggle the option to use arrows control along with WASD keys.
Other than this I liked it overall, and I admit I laughed a lot at the ending. I didn't expect it XD XD
To those who are struggling with jumping you can use X as alternative to K control. In the third level run as fast as you can to avoid getting hit by the bricks those people throw at you. The running mice were the hardest thing to avoid because the jump wasn't that high since Pico reached the limit of the level map.
Keep it up because I see the potential of funny and enjoyable games!
