Space to create a chi blast. Up arrow to jump and down arrow to duck. The left arrow does nothing. Hit the crates to gain points or jump over the cursed gem to gain a point. If you get hit by a gem you take damage you have 5hp so don't get hit. Congrats you found a secret if you hold the right arrow keys you gain a stream of points. It stops if you jump slash or duck tho.
Just me and some friends. Callum if your reading this I know you're going to make a better version of this. You might need to click the green arrow twice...
