I ended up buying the official Switch version of the game, and I'm enjoying it. The controls aren't terrible, and you can adapt quickly. Obviously, it's not as good or powerful as OpenRCT2, but it's nice to have the game in handheld mode.
Some people complained about performance, but it's just that when you zoom out, the screen scroll becomes "choppy", but the game itself continues to run well. It's just a problem with how the screen scroll works, it's only smooth at the standard distance.
Now I'm going to start learning how to play better because I'm a total noob and my parks are all ugly as hell.
