Use the arrow keys or the numbers 1 to 5 to control your ship. Aim to hit the green point balls and try to avoid the red crosses. You get combos by collecting points without missing, and hitting a red cross or missing a ball will make you lose your combo. Avoid the crosses as they take 1000 points off when you touch them. There are also speed up and slow down upgrades. More features coming soon.
Edited sprites speed 1.5 suits the game best here Cave story has great music
