Language!!!
Seriously, if you are not sure how to write in certain language do not make translations. Polish is very difficult language and simple translation "word for word" does not apply here.
The rest of the game was ok. I really liked the character and idea, but the game was too boring, monotonous. You have a lot of potential and you really should make a sequel.
PS. I criticized you for the awkward translation, but I am not sure if I wrote this review in proper English. :P
