I had fun with it and played to the end without any trouble. A couple of things that I noticed - There are a lot of cool upgrades, but because of the balancing, I never really had to think about what to spend my money on. I knew there would always be more money coming, so I just mashed any upgrade. I felt like there was time pressure even though there wasn't. The info panel for the upgrades kind of blocks the upgrade you want to click - having it a little higher might be good. Also, I didn't even realize there were trolley problem upgrades until the very end. Making them a little more obvious or notified / forced might give more impact.
