Thanks for playing the game and the review. I am fan of open world - exploration games and tried to fit the game jam theme into it via crafting an a delivery system but it was a lot to work in in 7 days. I am afraid some items suffered a bit. Now I have some more time I will polish those items you mentioned up.
I tried to optimize the performance but I only have a Quest headset to work towards which seemed to work pretty well but there is definitely some room for improvement. I am very sorry for the motion sickness. I am curious what platform you used.
I really appreciate you playing the game and hope you found enjoyment in it. Thanks.
BTW: The helmet was just a silly add on - no purpose but to amuse me in the wee hours of development time. :)
