Super cool game! For me it's a whole new sort of tower defence (ish) game, whitch I really like! Btw, your art is nice, kind of retro. Are you considering new uptdates or even a full release?
The game was part of a MakeAGameAMonth game jam so no plans at the moment for any updates, maybe if the game wins some traction will consider a bigger release but for the time being it will stay as it is.
