Really neat idea to have a dreamcatcher as a tower defence, and a pretty interesting take on a tower defence at that. Could really get into optimising how to play this in time with the basic but flexible set of tools at the player's disposal. Could use some visual indication of upgrades done to towers just to aid keeping track of what's in play. I wonder how many others will discover that clicking on the totem pole faces in the menu makes noises... Stellar job, well done.
