What a cool idea! I agree with Shrimp below, that having the chance to be "safe" with the exchange of time is a very cool mechanic. The top-down view is admittedly not what I expected from a VR game, but it was really interesting. It almost felt a bit like a virtual board game or something, it was very cool to get to walk around in a physical space and look down on the game from above in order to strategize.
Unfortunately, I did have a few nits to pick:
- I similarly had some pathing issues with the ghosts - though in my case, they seemed to get locked up around trees. One particular ghost seemed to get stuck in place, despite there being no obstacles, so might be possible there is a pesky rogue collider or navmesh hole that snuck in somewhere
- One of the red lollipops looked like it still had a box collider / wasn't set as a trigger, so it couldn't be picked up (I believe it was on the bottom right, near one of the apple trees)
- I had a little bit of difficulty with the controls in the beginning during the "bird's eye view" mode - I am not sure if it was an issue because I was using a Quest 2, but I found if I rotated the map all the way around, the controls would be reversed (ex: moving forward moved the character backwards), which was a little disorienting
Also, this is not so much a problem, but just that popped into my head while playing, if you ever expanded on this game in the future. But it would be cool if there could be some kind of "night mode" mechanic or something. Where ghosts would become more aggressive towards the player, but there would be more candy / it would be worth more points, which would expand more on that risk/reward mechanic you introduced earlier.
Over all though, I think this is such a cute idea, and I think kids especially could be really hooked on this "virtual trick-or-treating". I'm also seriously impressed you managed to get a proper gameplay loop done in such a short time period too! Great work.
