Not bad, but I feel it needs a bit of work and polish as it's a bit basic and not particularly interesting in some areas... here are my suggestions...

1. Some background music (SpongeBob-ish music) would be good so that the game feels a bit more interesting and SpongeBob themed...

2. Add in some character related sounds, for example if something happens to Patrick it can play a Patrick related sound.

3. Add in a character select so you can choose what SpongeBob character you want to play as... This can add some fun choice to the game.

4. Is this meant to be a race? If so, a countdown should probably be added such as 3,2,1, go! to make it fair. If a character dies the game should say who one that race and ask if you want to race again.

An odd platformer game but it's an interesting one and has some unique elements that make it fun

I platform game is very strange, Maybe you're not taking your game seriously, even though it's a fangame, you could polish your game more:

Have you ever heard of game juice? Study about game juice on the internet, and yes. Give your game a purpose, for example:

Objective that the character needs to face or achieve. I understand that you may be a child of about 10/12 years, But if your dream is to be the best at what you do, dedicate yourself to it every day

good game, i'd add A D key controls instead of just arrowkeys
