Played the first game and it was really good, i haven't played this game for long yet but it seems like it will be even better. My main issue is that you can't turn sound effects off, since i usually listen to other things while playing games. It would be great if you could change this but the gameplay is good.

So far its been pretty good. I payed for premium, so i can tell my full experience. The horror and difficulty increase is really well implemented. I really liked it so far tho! As the updates keep happening the game becomes much more better and is really well made by a single dev!

LOOOOVE THE GAME. The only problem I have is that it says I have to pay for the next levels which is really annoying. But absolutely perfect and fun to play!

Thank you very much for your comment. I am sorry to bring the premium system. But I need financial support to continue developing new games. Which country do you live in? If the pricing seems high, I can review it.I will remove the premium lock with the update. The new update will be live in 1 hour. You can now play for free.
