Well, it certainly lived up to the hype :D
Really really cool. I really loved how it gave us the opportunity to set up different weight classes so there could be the classic, heavy-hitting tank paired with the lightning quick but weak runners, made for some really interesting problem solving.
Also a very unique way to force the player to think. We're all so used to only thinking about maximizing our tower's performance OR maximizing our attack, so to try and find balance was a great challenge!
Obviously it could be easier to understand with a bit of a walkthrough/tutorial, but honestly I quite enjoyed poking around and figuring out how it all works. And as you said in the description, it is very addicting.
Really impressive!
