Glad you liked it!
For the transparency part, my bad, I didn't think about the shopping part at all haha
For the items, there are 3 types of items generated:
- Those neutral (for example that gives you more money for a certain type of customers, and less for another)
- Those that make the game easier overall (makes it harder to get excellent, or to earn money, but easier to hit great notes for example)
- Those that make the game harder overall (gives you more money, but notes get harder to hit)
So the goal is that:
- if you think it's too easy, you can increase the difficulty to get more money
- if it's to hard and are missing too many notes, you can make it easier by decreasing the difficulty and get more money that way
- if the difficulty is good for you, you can try to optimize your earnings with neutral items
Talking about customization, if you download the game, you can actually change the musics and make your own map by modifying the jsons in the save folder (somewhere in %appdata)
