I've been playing it too. Found screens of one of my old parks, soo much nostalgia, it feels like 2003 again. I really liked to make realistic parks. It was a thing to make a new map yourself and build a park throughout the decades, where each update was a new year with a new ride or thing.

You can: get infinite money. Build through things (this can potentially glitch your save up though). Get batches of guests, you can deliver 1000 guests on your doorstep. Give all guests park maps, umbrellas, lots of money or food. Change the weather. Fix all the rides. Make everyone happy.
Tip: get as many guests as you can. Put them on a 1x1 path over water with No Entry signs. Give them all balloons. Remove path and let them all drown. Now try to pop as many balloons as possible before they go out of your screen.
