I burned the idol :)
I definitely see what you were going for here, and it was a huge experience you were trying to craft. Multiple large locations, an open world hub with the swamp section. It's a shame you didn't have a chance to finish it because the concept itself is cool.
In terms of whats there, when actually exploring the movement felt good however the the sheer size of moveable area meant I wanted the option to move a bit more quick (Like being able to spam forward and speedup/skip the move tween) just to help getting around, especially where I need to backtrack. The actual environment design that is in place is really good, It's clear that had you the time these environments would have been filled with set dressing and interesting immersive spaces to explore.
In your description I see you're planning on taking this forward post-jam, and I definitely think you should because you've clearly got a complete vision and just didn't have the time to execute.
Good effort!
