Hey, thank you for your feedback and the time to play our game. We are terribly sorry for the bad tutorials, we will surely fix it in our planned update! As for the health pills, we should have mentioned it somewhere but the changes in the value of the health pill is a mechanic which gives you a random value of health for a random cost. Same is true for other pickups (except soda cans which gives a random value for no cost) and interactables. It's all part of the world's psychedelia. What you pay for items and what you get depends on luck.
