To set the scene: I played for roughly half an hour, and managed to make it to day 5.
Firstly some bugs:
If I open a menu (let's say the illegal shop) and hit escape, it unlocks my mouse and brings me to the pause menu. From there, if I exit the pause menu, my mouse is locked again but I still have the shop window open.
Again, with the pause menu, if you pause the game, and click "Exit", it takes two escape presses before the menu comes up again. I'm guessing it has to be because of some "pauseMenuActive" variable not being toggled by the button.
You can interact with most things through colliders. This made it really easy to accidentally try to pick up an item in a purchased box instead of the actual box. Bonus! You can turn on/off the radio through the refrigerator.
There is also a method to duplicate hot dogs. If you line up two buns so you can drop a wiener perfectly so it hits both buns at the same time, it makes two hot dogs. This way you can focus mostly on buns, and don't need to purchase any hot dogs until the first purchased box of buns is all used up.
I don't know if this was a bug or not, but I got taxed $0, and never met the guy again.
Guiding the player
At first it took me a while to understand that all of your wieners and buns start out moldy, and there's nothing you could do about it (at least, that's what I'm guessing, because putting stuff in the sink gets blocked by an invisible collider). While the sausages were easy to see when they were done cooking, the buns were a different story. Either you can't see it, or it's a pretty small difference from the uncooked to the cooked (if there even is one, or if it's a huge troll cooking the buns). And from experience, it seems like the buns gets burnt much faster than the wieners.
The first time I played the game, I didn't know that there was a shop (even though it becomes pretty obvious when you exit the truck), and again with the moldy stuff I think even a small tutorial would enhance the player experience, so most people don't have to figure out the mechanics of the game they chose to play, and get frustrated. (At least, if you're not expecting everyone to come from the video).
I also think the difficulty scaling is a bit steep, because I can't see myself ever acquiring the Dirty Accountant upgrade, as you'd have to sweat pretty hard the early days before rent becomes $80+
And one last thing from my playthrough, I actually never got over 3 stars. I made loads of money (getting up to $130 the first day), but never got a higher rating that 3.
Playtesting is pretty crucial to creating good or even great games. And I've said this several times, but a friend, family member, or a dedicated game development discord server are all great options for just another perspective. Because as a game designer, it can be difficult sometimes imagining a beginner play your game, and get in their shoes without seeing anyone else than you play it.
Good luck on future games, and I hope the video is received well!
