i do the right method for completing a level, but somehow when the holograms are on top of me somehow they just all of a sudden run faster than me and fall off. i've been dealing with this for quite a while now and it's keeping me from beating the level with the green force field floor.
other than that, awesome game. 5/5
finished (every badge, too) in about 10 minutes. needs a couple more levels and (going with OnigiriChan's idea) needs bonus levels after each star is collected
when you can't fit a cannon tower or something into a tight space (like in my case, between 2 storage silos) then you can find a way to rotate the cannon tower to change the length side of the tower to the width side and vise versa. press [+] so that the devs see this
