I'm glad that mechanics is fun! :)
Is there anything you would like to improve?
We have to write in game "press R to stasrt the level again" so people know how to refresh the page and retry. Some people got stuck at the first level because they don't know the command. We'll fix it!
We want to explain better in game how you can use weight, strenght, speed and jump to overcome obstacles. They are not always so obvious.
Thank you for you answer, you are very kind! :)
