I translated the comment to English and it says "Great short game, sad too, I hope more games like this come out, good luck on further construction!"
Now, my reply...
Thank you so much for playing the game. The game has dual endings though. One is the sad ending, the other is a happy one. Do try it out and find a good ending. The hint for it is basically focusing on the voice at the end, you will have a clue for yourself. The devil is in the details ;) Thank you once again.
