Use the arrow keys or "w" and "s" to move up or down. As you try to avoid the spikes, try to collect as many hearts as you can to try to beat the high score. This game is not mobile compatible (sorry). If you find any bugs, please let me know and I'll try to fix them. I hope you enjoy it!
I had my dad help me with this. He is an excellent programmer, and he taught me how to program this game. We made it with all of our hard work. (by the way this is the very first game I ever made so it's really simple sorry about that)
