*Important* Sorry about that, you can change the arrow colour with the numbers 1,2,3, my bad for not making it as obvious as I hoped to.*
In adventure mode, make sure to play through it all, there is a surprise after so many hearts go by. The bar in the top left shows this.
You control Cupid and shoot at hearts in two different modes of play, Adventure and Survival. Read the instructions in game for more information.
Background scenery is random, so it's possible that you will get some crazy patterns. (Record of five stop signs in a row)
I left the right click menu in, sure you can screw up the game by advancing frames, but it's not going to help you much. Also I'm sure people will want to zoom in on my awesome artwork. I'm joking.
I've tested my game, but if you notice any bugs or have any questions leave them in a review and I'll try to reply.
Hope you enjoy playing!
