I must say while it certainly channels Limbo it sure looks very nice and all the interactions seem to work great.
With some more original physical things to do this could be pretty damn cool.
I wholly agree!
But this isn't a bad thing. It's the opposite, looks like a very interesting concept to build upon.
Congrats! Great work, Meister!
In fact, I'm also from Brazil and I work as a game writer, designer and researcher. I'd love to contribute to the project by helping with more puzzles and fleshing out the narrative design and story.
Let me know if you're interested!
