I've been making games in Bitsy Color 3D lately, and looked through the itch tags to see what others have done with the engine. This is amazing! Skewing a number of tiles together to construct models, like the bottles and the bugs, is something I've been experimenting with as well. It's crazy what this engine can do if you convince it to, and you did a great job taking advantage of everything.
There is some z-fighting in the canopy which could be fixed relatively easily, and I think the open ended nature of the world makes it a bit disorienting in first person 3D, but the atmosphere is great.
I was wondering how you managed to collect an item in one shot when its made of 3 tiles? The bottles and mushrooms I mean.
