Okay so this is why noone plays Tetris jenga!
Cool game, lots of fun. 25 height is my best. Love the music and the creativity of the idea. I enjoy the way the camera pans down so you can see whatever is left of the base of your tower after a fall!
What holds me back from full 5 stars? Well the graphic design is probably a bit toooo minimalist. Wouldn't have minded having a grid in the background to help align the falling pieces. But the biggy for me is that a good or bad run is so reliant on your luck with the RNG! Now I think that's inevitable to an extent in a game like this, but there ought to be a way to give the player a feeling of knowledge or control that can compensate for it? For example it wouldn't be extreme or give too big an advantage for the player to know in advance what the next piece, or even couple of pieces, might be. That would actually enhance the game in a way, by making the strategic side come into play more. You can't really do a lot of planning in advance when you don't know what the next piece will be, particularly if you have the bad luck to get one of those crosses!
EDIT new best of 31, do enjoy watching the towers collapse at the end - one of the redeeming features of the game is that it's actually kinda fun to lose!!
