Hello there! I am a new “developer” around here, but I consider my coding skills to be fairly decent. I have been working on this game for quite some time and I invested lots of effort and hours into it. I tried to make it feel good and to give some fun to the player.
Keep in mind that this is only my second game, but I plan to take every criticism and suggestion into consideration. Also, I am mostly a scripter, so excuse all of the free models and not so good of an UI (I also used some free assets for some UI pieces). 
I know it has the word “Tycoon” in it, but I tried to make it fairly different from the casual no-effort ones while at the same time still containg the same core principles (at least I hope that I have managed to do so).
I was wondering what should be changed at the moment before I buy an Icon, a Thumbnail, two ads from a graphic designer and before I start spending robux on the Roblox advertising system.

In the upcoming updates I plan to add: at least two more floors(if not more), daily rewards, rewards for group members, rewards for Roblox premium users, a Rebirth system(restarts player’s progression, with the benefit that they earn a higher percentage of in-game revenue), global leaderboards(to create competition between players and increase play-time mostly for the players that grow to care more about the game), a chronometer for the mazes and the obbies with a leaderboard for each that shows the fastest players(it could not be such great idea because of hackers that can increase their walkspeed?) and if it will not surpass my skills very much: a pet system.
What do you think I should change? Does the progression feel satisfying? Is it feeling too hard, too easy or ok/could be better(insert opinion for improvement here)? Are the prices for the gamepasses and devProducts fair? The devProducts ones seem to be a little cheap, but in the beginning I think it is better to have cheaper than fair prices, at least for cash. (or should I change the prices to gain more of a profit?)
I think I want to target it more toward kids, so that they can also learn something beside playing with their brains switched off. At the moment, only two blackboards do this, that you have to solve mathematical calculations. I plan to add at least two more “brain boards”, one for chemistry and one for physics. These two will be multiple choice, so that even if a player is 4 years old, it should not be that big of a problem. (the questions will be fairly easy, something like "What element does C represent? Argon Oxygen Carbon Potasium". And something similar to the physics one.)
