protip: put a marksman on the last turret spot on every level. that way, if an enemy breaks your defenses, they will die before they can escape. works for me every time.
this is an excellent tower defense game. there are many fun and unique elements most others simply don't have. I like how some enemies have weaknesses and resistances to certain towers, so you can't just cover the map with one tower type. i would love a sequel, and it should have more tower types. possibly a freeze tower, poison tower, etc. all in all, i rate this game 5/5 stars. :)
to fireballshadow: to beat the spike room level, grab the ledge when the gaurd throws you off. then,shoot him with ur pistol. then click on the body, and you'll throw it in the spikes. jump on the body, then to the door.
