I am playing your 0.3 version, it looks amazing! And the world is huge.
I think I have a glitch, I am at the beginning of the game and I can no longer get back to the minigame where I have to light some torches. There is an invisible wall before the entrance of the game area. I have attached my savegame to this message.
I also had a few collision issues when scrolling between maps (I am often stuck in a tree when the new map starts), I can make a video to show you if it can help.
Also, I was able to reach a large part of the huge forest at the west, I am not sure if it is normal to go there so soon. I got the mushroom, I went in a dungeon in this forest, I also talked to Gerudos
Anyway I will continue to play (I noticed I can traverse walls with control), keep up the good work!
