I tried "Block Off" - a 3d version of tetris is something I really like. I think you should add an indication of where the block will drop. I don't know where the current block's exact position is, it's hard to tell which "nearby" points correspond to which "far away" points.
Here is my game

Hello. I already have played your game for a while days ago, before opening this post. Played it again now and will give you my feedback now:
I really like the title a lot "The magical Cave adventure" sounds very catchy and has a lot of potential. Also the game itself is very nice. I also like the "I´m stuck" button. The wooden shields are also nice and the "mini map". But I would strongly suggest to do something about the graphics, music and mouse control. The graphics is not really appealing, I would suggest to check out the unity store, here you can buy complete and professional made levelpacks and characters for 2d games for just a few bucks. The music is not bad, but way too short. About the Mouse control: I would change it in a way that you first have to click somewhere and then the character moves slowly to the target. Also you could animate the character. One last thing: The Fullscreen Button does not work on my system. Hope that helps.
