Sadly there's no web version for this game because it's really really nice! I tried to find a TD and didn't find anything interesting to play, happy to see others that had such great ideas!
I really had fun discovering it but I find a nearly optimal spot that doesn't need me to move (or really rarely), I'm more than 900 seconds right now and losing one life every 60 seconds I guess :D. Ruining my game :p.
The base idea is nice and well implemented. I'd be happy to see more of this game, with turret building and more maze shape and ennemies! If one day you decide to push further this game, don't hesitate to pm me!
But as others I agree, early on it's too aggressive you don't know what to do and the red things on tress shouldn't have been red, but that's details.
