What's this online game called?

k theres this game online thats really addicting and I have noooo clue what it's called, it's a stupid game but it's fun. anyway the game is about making things with elements like oil,firework,glass,block,stone,water,fir… and metal, you get this little screen (very pixily) and you can create bombs and stuff using the elements in the bottom box, people make pixel art and minigames on it that they can share with an acount. anyone have a clue what this game is and were i can find it.
