I am also a Unity developer. This isnt BAD, but it needs a bit of work. I recommend, camera ( cant give away all my secrets but think WoW, needs to move in when colliding with walls etc ). Doors need colliders so that you can use things like OnTriggerEnter functions so that when you get close they open / close. Keep up the good work!
i noticed that in burger ping, if you click make burger more than once it gives you one burger but takes 10 snails. It also scales e.g. 4 clicks takes 20 snails but only gives you 1 burger etc... Good game though its something i can do while im sitting at work creating API's for the game im working on.
I am also a unity developer, and i must say. This is probably only the second unity game ive seen so far that impressed me. DARN good job with this one. I love the personal turret, its something ive wanted to see in a TD game for a long time. GJ!!!!
Thanks :)
