Thanks for playing! When you start the game there is an explanatory tutorial of each thing, the collectibles are hearts that give you points, you don't have to take them all are for the final score , and the clock to be able to go slower and the infinty to collect a lot at once, the issue you say of losing by extending yourself too much is the right bar above, which goes down after you extend the line, You can also retract it to win a little although you only win 33% of the cost, anyways thank you a lot for playing it and giving me your feedback
