Thanks for your feedback! :)
Okay, I'll consider adding an endless mode to the game.
Yeah, I guess that kinda is a problem that the player slides because I am using a rigidbody. I've noted the problem and will fix it soon.
Which fan do you mean? There's sort of a launcher or the normal fan. I've made it so the fan turns on and off with a press of a button. So if you press it twice, it turns off again. The launcher was designed to switch directions again after a few seconds. So you have to make a run in order to get up.
