After one day in the wild I know that the game is not that easy for players as I thought. I didn't want it to be obvious and I didn't want it to be as hard as all the japanese room escapes (lots of them in my opinion don't make any sense). My idea for the game was to make the game which player can finish without a walkthrough in 20-30 minutes. Now I think that most of players don't want to play the game longer than 5-10minutes. Rookie mistake (that's my first game). So please forgive me if my words "The game is easy. Walkthrough is unnecessary" at the beginning misleaded you.
Anyway one more time thanks for playing and I still hope you're gonna' make it (at least almost) without a walkthrough :)
