Rise of Lava

Alright, listen up! The lava's rising fast, and you gotta get out of there ASAP! Grab your friend and start running for the hills. The lava's not slowing down, so you better keep jumping to higher ground. Oh, and don't forget to collect those emeralds - you're gonna need 'em to get a sweet costume. Just make sure you and your buddy both make it to the high ground in one piece, okay? Don't you dare let the lava get you!

Use the good old WASD keys to move and jump in the game.
Or, if you're feeling fancy, try the Arrow Keys instead.
*And if you're on a mobile, you've got controls for that too!
