Great Sperm Race

This is the journey of a sperm to the egg, race to the end and learn about how it all works. Millions die and only one can make it, Is it you? Try to keep your distance from the sticky walls of oozing acid. Touch them for too long and your little squirt will die. Use the ARROW KEYS to move and press SPACEBAR to show map to help you find your route. Good luck!
