No there isn't. There are some things that you can do to make things easier though.
You can choose to ignore the girl who offers to give you a tour of the school. It's better to ignore her.
It is very useful to grind your Biology talents.
- Brain Basics gives you extra talent points so you will grind faster. Not sure if it's a flat increase as stated by the girl who gives tips or a % increase as indicated by the tooltips.
- Greater Metabolism is also a good skill as it converts food (yellow) and water (blue) into Energy. You will have more energy to do stuff if you increase this skill.
- Nimbleness is nice to have, it's a simple increase in running speed.
There aren't a lot of useful skills on the Business talents.
- Cryptominer is nice to have if you have maxed it out. That only works if you pay rent and wake up in your room. If you max it out and wake up in your room everyday, you get 70 coins (10 coins per day), effectively making rent cost 30 coins (100 - 70).
You need Energy to do stuff. Working for coins requires energy for the most part.
- You need about 70-75 energy to work a normal job at Goodies, the bakery. You get paid 70 coins for the shift.
- You can work there with less energy or while you stink but you will clean the toilet instead. The floor must be clean enough (no dirt spots) for April, the shop owner to let you get paid. Your pay depends on your tips.
- The food bar is yellow, water bar is blue. If you eat and drink, the bar turns green and you consume that to recover energy.
- You can look for food in garbage bins, water from the pond in the Goblin village.
- There is a girl who will give you cookies from time to time. The effect of the cookies when you eat it as she wanted will depend on your Uni girls Reputation. (High rep = energy boost, Normal rep = Nothing much, Low rep = Lower rep). You can choose to eat it later and it will function like a normal cookie.
- To get to the Goblin village, head out of the school and turn left. Follow the path all the way. The Goblins are very easy to fight (their leader is very hard though). You even get half a bread if you beat the Goblin guards.
- There is another unconventional way to get food and water behind the dorms but it only works during daytime.
