some excellent feedback thank you kindly..
Firstly the salary cost for additional workers does continue to grow as you level those workers. I can look into raising it less or tightening the growth curve, I don't want the monthly costs to overwhelm you. I will def take a look at this and see how I can tighten it up.
In regards to the long term investment bug, It is suppose to notify you and then move the cash into your bank not petty which is possibly why you didn't notice the cash or its possible it didn't add. I will perform some tests to ensure it is adding the cash as intended.
I agree with you on the petty / bank feeling odd. The main reason for this was so the player had to choose to put money in the bank to get interest, but I agree it does feel some what off. I might just shift it back to one cash flow and let you open an account for some sort of fee or unlock to start gaining interest or just let it all auto bank. I def agree though the idea is cool but in reality the 2 diff cash streams plays odd.
The Contract work does need some tweaking on it's procedural generation, some of the results can be a little wild. The one issue here is if you use the RUSH worker skill contract work is pretty easy but without it's pretty difficult. I will work to balance this more for sure.
The help section was deadly accurate when I first wrote it back in Ver 1.0 but in the current version things have shifted a bit balance wise it now does require an engine with 6 tech in year 2. I haven't updated the help section I honestly wasn't sure anyone had read it, you are the first to mention it and I will rectify that shortly.
Everything is still on the table and balance will shift like water based on feedback from great people like you. I truly appreciate you taking the time to try the game and provide feedback I hope you enjoyed your time, and I hope you try some more with future updates. Still a long way to go but I have a lot of big ideas for the game and I hope you enjoy them, as well as If you have any ideas I am more than open to hearing all of them.
