Bear in mind that this is my first EVER game and it was made in pure java with only LWJGL. You are a miner. You have got stuck underground in the middle of a volcanic eruption. The lava is rising and you must flee. If the jar file does not run when you double click try running it from CMD (java -jar LavaQuest.jar) and do not use runnable.jar WASD to move. Cheats: M,N,B,K Download the zip from Google drive and extract it. Then either run the .jar file OR the correct executable for your OS.
The coin sound was a bit too loud, it seems like when you hit a coin block multiple coins pop out, so I guess that's why. Also the jumping and graphics are a bit derpy, but other than that you did pretty good.
Nice game.
