I like the environment. Pretty nice looking "low-poly" style. Was fun walking around end discovering your little "villages".
Unfortunately somehow the fighting seems not to work. The enemies feel extremely overpowered. As soon as one of them discoveres you, game is actually over^^
So just could walk around, discover everything and collect these bottles, but not sure for what to use them. Also because couldn't beat the enemies yet, not sure, if there would be any more story-elements later and/or if it would be more related to the theme then...
So all in all, guess it's actually really just a "prototype" like you described it, and not sure if it can be really rated in that state, but anyhow thought i give it a try.
If you continue, you at least have a nice enviroment already :-)
