Run, jump, and collect through 30 levels of increasing difficulty. Make sure to avoid pits, falling spikes, and pesky laser beams. Have fun! Try to collects as many hearts as your can (within a single run of a level) and complete the levels as quickly as possible to get a higher score for each of the three difficulties. Once you have a positive score, you can submit it to the scoreboard and compare it to everybody else. (Scores less than 0 will show as 0, and you will not be able to submit them.) Each heart is worth +100 score, and each second you take is worth -10 score.
