Fun game for real, couple of improvements could be made tho! first off the blocks should show edges of where the block ends, now when you have 2 greens on each other, you can't see the difference. Also it begins very slow with little action, only until level 9 it got harder and my tower collapsed, would be nice if it started higher.
Also would be cool if you could see the results of your previous completed tower, i fell down once on accident and it was cool to see all the damage that was caused. On the end you just teleport away everytime, would be cool to see the tower behind you or below you.
