Fantastic. Instant applause. This is such an incredible game. I can already see, if you were to polish some of the problems out, this would be such a hit with the causal gamer community and you could easily make some money.
So you probably already know the following problems, but if these were to be addressed, you'd have a wonderful immersive experience:
Collisions. Just a small collision at the base of each tree and caravan to stop you walking through it goes a long way.
Tile layering. There are multiple instances, more so after you've changed the environment, where the object or environment piece is on the wrong layer relative to the player.
One addition I would make is an animation going into the water. At the moment, you just walk into it. It would add a lot more if you were to have the character stop, step down, then give the control back to the player.
I would also add some indicator that you can put the items back in the caravan. I did not realise that until I did it accidentally.
The visuals are beautiful, the music is fantastic, this is one for the portfolio. Incredible.
