This is a nice little tower defense game. It seemed like there were some interesting ideas in it but I had a lot of trouble figuring out what exactly was going on beyond the most basic tower building mechanic. Even that took quite a while to work out since the first thing I clicked on was a weapon which was useless without a tower to put it on and I had to back out of the game and look at the instructions again to figure out that the space bar would deselect it. I would expect clicking on the tower builder button to deselect the weapon if I have it selected.
It was unclear to me what the dice rolling mechanic did. Did it effect all towers? Only the selected one? Was it temporary? Since I couldn't see the stats for any individual tower it was hard to tell.
I also couldn't work out what was different about the different colors of tower. Maybe the more expensive ones did more damage?
