Just wanted to post an update letting you know about a number of bugs I've run into over the last week or so.
1) I'll start with the most gamebreaking bug I've found, which is on Reality TV Island. Everything's fine up until you get on the show, and at that point, it becomes really difficult to beat, if not impossible. To start with, several of the challenges have messed-up framing, where the original square aspect ratio hasn't been correctly adapted to the wider, more rectangular format. (This is a recurring theme in several of the bugs I've run into.) Sometimes that's just an aesthetic issue, but other times it actually seems to be affecting the functionality of the game. In particular (although this may be unrelated to the aspect ratio issue), the Turtle Toss challenge stops working after the second person makes their throw. As in, no one else makes any throws, so you just sit there with nothing happening until you decide to quit out of the game.
2) The messed-up aspect ratio also causes an issue with the final boss fight on Counterfeit Island, making it super hard to catch the falling artwork. It's technically completable, but it's about twice as hard to beat as it's supposed to be, because the movement controls don't work if you click in certain spots.
3) Earlier on Counterfeit Island, when I was looking through the security footage and my character says, "there are hours and hours of footage, I need to go find the security guard to know which timestamp to check," I was unable to close out of the security footage; there wasn't even an "x" to click in the corner. I had to quit out. Not gamebreaking, just annoying. Similarly, I had trouble closing out of the computer game in the Internet cafe after losing.
4) Not sure what caused this, but on Astro-Knights Island, I lost all my progress on the island when I saved and quit, after playing all the way to the ice planet. I had to do it all over again. The game had repeatedly given me the autosave notification in the corner while I had been playing up to that point, and I clicked "save and quit" when I left the game, so I don't know why that happened. It was just one time, so it could have been a fluke, but I thought it worth mentioning.
5) Similar to the earlier bugs mentioned on Counterfeit Island, I wasn't able to close out of the newspaper on Big Nate Island that shows up when you find the time capsule; the "x" didn't work. I closed the game and replayed that part, and it worked the second time for some reason. But that type of thing does seem to be a recurring bug throughout the game.
6) Also on Big Nate Island, if you lose the paper football game, you get the spinning blue wheel of death and can't do anything.
7) Finally, when you defeat Director D on Spy Island, you get the spinning blue wheel of death and can't progress. If you save and quit and then reopen the game, your progress is saved, so the island is technically completable, but it's still irritating.
There are a variety of other bugs, too, but I didn't bother mentioning them because they're mostly just aesthetic issues (framing errors that don't affect the gameplay, lack of music or sound effects in certain scenes, etc.).
